Amino Acid Chart: Explaining Each Kind


Amino acids play an indispensable role in many body processes. It’s also called the “building blocks of life” since our bodies can’t exist without them. Overall, a human body needs 20 amino acids to function properly, which we discussed in detail on the amino acid chart below.

If you want to know about amino acids and how they work inside the body, read on to learn more.

What are amino acids?

Amino acids are a kind of organic compound that serves as the building blocks of protein.

It’s involved in critical body processes, including the growth and repair of body tissues, muscle building, energy production, the transmission of brain chemicals, digestive health, immunity, and so on.

Moreover, amino acids are divided into two categories: essential and nonessential amino acids.

Essential amino acids are those that our bodies can’t produce naturally and must be acquired through diet or supplementation.

On the other hand, nonessential amino acids are those that our bodies can produce on their own. Some of these nonessential amino acids fall into the ‘conditionally nonessential’ sub-category since supplementation might be needed in certain conditions.

But why is it called nonessential? Does it mean you can live without them?

Actually, no. It’s called ‘nonessential’ because it’s technically unnecessary for us to get it from external sources. Still, it doesn’t mean it’s not essential for bodily processes. 

Overall, we need both these two amino acid categories to have a healthy and functional body.

But how many types of amino acids are there in total? There are over 500 amino acids found in nature, but only 20 are directly encoded into human genetics.

Types of amino acids and their functions

Of the 20 amino acids we need, our bodies can’t produce nine of them. This is why amino acids are popular ingredients in IV therapy drips

But amino acids are more than just their collective term. All 20 have a unique name, specific functions, and amino acid structure/classification.

Essential amino acids list

Essential amino acids can’t be synthesized by the human body, so they must be taken through diet, supplements, or IV therapy.

So how many essential amino acids are there? Below are the nine types your body needs:


Histidine (His/H) is a basic amino acid necessary to form histones, a protein that provides structural support to chromosomes.

Also, Histidine is a direct precustor to histamine. It’s a neurotransmitter involved in body processes like gastric acid secretion, inflammation regulation, and release of neurotransmitters in the brain.

Moreover, this amino acid is involved in pH regulation, immune function, metal ion binding, and nerve function.

Histidine is often obtained from food items like whole grains, seeds, eggs, legumes, and dairy products. Aside from that, you can also receive it as an addition to your Immunity IV Therapy or Energy IV Therapy.


Isoleucine (Ile/I) is an aliphatic amino acid involved in blood sugar regulation by supporting insulin production. It also takes part in hemoglobin production.

Aside from that, Isoleucine is part of tissue repair, which promotes faster wound healing. It does so by aiding collagen production, an integral component of our connective tissues.

Isoleucine is also part of dopamine synthesis, a hormone involved in mood regulation. It can also improve immune functions and metabolism.

Some food items rich in isoleucine include lentils, beef, pork, chicken, tofu, and peas. If you want a dose of isoleucine without adjusting your diet, you can get it through IV therapy.


Leucine (Leu/L) is another aliphatic amino acid that takes part in tissue regeneration, protein synthesis, and metabolism.

Also, it aids in faster wound healing by promoting collagen production. It also helps strengthen the bones and increase the production of growth hormones.

Moreover, leucine helps the muscles recover after strenuous use. This includes intense workouts or prolonged physical exertion.

This amino acid also increases glucose utilization in the muscles while boosting the production of insulin.


Lysine (Lys/K) is an amidic amino acid, which is widely popular for boosting calcium absorption. This directly strengthens the bones and teeth crucial for young kids and the elderly.

Aside from that, this amino acid plays a big role in collagen synthesis. Lysine is also involved in carnitine synthesis, which is essential for the transport of fatty acids during energy production.

And like other amino acids, lysine contributes to immune functions and wound healing.


Methionine (Met/M) is a sulfur-containing amino acid beneficial for detoxification and tissue growth.

Moreover, methionine helps in the absorption of minerals like selenium and zinc. It also works as an antioxidant that protects the body from damage.

Aside from that, methionine is believed to reduce fat accumulation in the liver.

If you wish to increase your methionine intake, tuna is a good choice. Shrimp and salmon are also good sources of this amino acid.

But if you want to skip the hassle, you can also get a dose through an IV therapy session.


Phenylalanine (Phe/F) is an aromatic amino acid involved in the production of various neurotransmitters. This includes norepinephrine, epinephrine, and dopamine.

Also, phenylalanine is crucial in the production of melanin, the pigment giving color to the hair, skin, and eyes.

Moreover, an ample supply of phenylalanine can help improve a person’s memory and maintain a state of wakefulness or alertness. 

Since phenylalanine boosts the production of norepinephrine, it will also indirectly reduce hunger pangs.

Lastly, this amino acid also aids in producing endorphins, also known as the ‘natural painkiller’ of the body.


Threonine (Thr/T) is a hydroxylic amino acid used by multiple parts of the body, including the teeth, skin, muscles, digestive system, and immune system.

Aside from that, threonine is being used to treat indigestion and other intestinal disorders. It’s also believed to help reduce the symptoms of anxiety and depression.

Threonine also helps in the formation of blood clots when a person sustains a wound.


Tryptophan (Trp/W) is an aromatic amino acid and is a precursor to serotonin, also known as the ‘feel-good hormone’. This hormone is integral in regulating sleep, mood, and appetite. Also, it’s crucial in bone metabolism and proper blood clotting.

Aside from that, tryptophan is part of melatonin synthesis. Aside from adding pigment to your skin, eyes, and hair, melatonin also impacts a person’s sleep and metabolism.

Tryptophan also plays a big role in niacin (vitamin B3) synthesis. This vitamin is crucial for energy production and a myriad of bodily processes.


Valine (Val/V) is an aliphatic amino acid necessary for protein synthesis, brain functions, muscle repair, blood sugar regulation, and more.

Moreover, valine is a branched-chain amino acid (BCAA) that can be converted into energy. This often happens during intense physical activity, where valine is broken down into glucose, which serves as an immediate energy source for the body.

Also, this amino acid is involved in the production of gamma-aminobutyric acid (GABA), which is necessary for relaxation and healthy brain activity.

Valine also helps regulate blood sugar levels by stimulating the production of insulin.

Nonessential amino acids list

The amino acid protein chart will not be complete without the nonessential group. Below, we discussed the 11 nonessential amino acids that the human body can synthesize on its own.

But despite the body’s ability to produce these amino acids, some may need supplementation.


Alanine (Ala/A) is an aliphatic amino acid that can be used to break down another amino acid, tryptophan.

Like all amino acids, alanine plays a crucial role in protein synthesis. Most proteins have alanine as their major amino acid component.

Since alanine is glucogenic, it can be converted into energy in the liver when the muscle proteins break down.

This amino acid is also involved in regulating blood sugar, muscle building, energy production, and immunity. Also, sustained release beta-alanine is proven to aid with heart health.


Arginine (Arg/R) is a basic amino acid that falls in the conditionally essential sub-category. It means that the body can produce some level of arginine, but it still needs supplementation from diet from time to time.

This amino acid is involved in nitric oxide synthesis. This molecule regulates blood pressure, blood flow, and cardiovascular processes.

Aside from that, arginine is necessary for hormone production, including growth hormones and insulin. This can also regulate testosterone production, which is a big part of muscle growth among men.

In addition, arginine can help eliminate excess ammonia in the body. Ammonia is a by-product of protein metabolism, and high levels can be toxic.


Asparagine (Asn/N) is an amidic amino acid that breaks down toxic ammonia from the bloodstream.

All body cells need asparagine for proper functioning. It’s also crucial to keep an equilibrium in the nervous system to prevent it from being too calm or nervous.

In fact, asparagine deficiency can lead to confusion, headaches, irritability, and even psychosis in the worst cases.

Although amino acids are often found in animal sources, asparagine is available in huge amounts in plant sources like legumes, nuts, and potatoes.

Aspartic Acid

Aspartic acid (Asp/D) is an acidic amino acid involved in various nervous system functions. It is a precursor of nicotinamide adenine dinucleotide (NAD), which is an integral compound for hundreds of physiological processes.

This amino acid helps regulate the NMDA receptor, which is crucial for memory and learning. It’s also integral for the proper transmission of signals between neurons.

Aside from that, aspartic acid plays a significant role in metabolic regulation and immune system functions.

And like other amino acids, aspartic acid has the ability to detoxify ammonia from the body.


Cysteine (Cys/C) is a sulfur-containing amino acid that acts as a powerful antioxidant. It’s a precursor to glutathione, a substance that eliminates free radicals from the body.

Moreover, cysteine provides immune system support since it’s involved in the production of white blood cells and antibodies. Both these chemicals fight off infections.

Aside from that, this amino acid detoxifies heavy metals like lead and mercury. It will also speed up the healing of wounds, thanks to its role in forming collagen.

At the same time, cysteine also supports skin and hair health since it’s a component of keratin.

Glutamic Acid

Glutamic acid (Glu/E) is an acidic amino acid involved in a myriad of bodily processes.

First, glutamic acid is an excitatory neurotransmitter that plays a big role in learning, cognitive function, and memory.

Aside from that, this amino acid is a part of the acid-base balance system of the body. This stabilizes the pH level of various bodily fluids.

In addition, glutamic acid is involved in nitrogen metabolism that breaks down compounds like nucleotides and neurotransmitters.

It can also be converted into glucose to serve as an instant energy source for the body. Lastly, glutamic acid is responsible for maintaining the integrity of the blood-brain barrier, which protects the brain from harmful substances that could be present in the bloodstream.


Glutamine (Gln/Q) is an amidic amino acid that has a crucial role in a person’s intestinal health. It supports the integrity of the intestinal barrier to block the entry of bacteria, toxins, and other harmful substances.

If you’re prone to stomach upset, this amino acid and our Stomach Flu IV will complement each other.

Aside from that, it’s part of the acid-base balance system together with glutamic acid. It maintains the bodily fluids’ healthy pH to prevent irritations or disruptions.

Unlike other examples of amino acids, glutamine has the ability to cross the blood-brain barrier. It can be metabolized into glutamate, which is a vital neurotransmitter.

In addition, glutamine helps in muscle recovery, especially after intense exercise or when you sustain an injury.


Glycine (Gly/G) is an aliphatic amino acid, which is a key component in the connective tissues found on the bones, skin, and cartilage.

Aside from that, glycine is an inhibitory transmitter that regulates memory, cognition, and sleep. It also prevents neurons from firing up.

This amino acid also has an anti-inflammatory benefit, especially in the gut, and can aid individuals suffering from inflammatory bowel disease.

Moreover, glycine has detoxifying properties and the ability to slow down signs of aging on the skin.


Proline (Pro/P) is another aliphatic amino acid that supports cardiovascular health. It maintains the structural integrity of blood vessels, directly reducing a person’s risk of cardiovascular diseases.

Aside from that, it’s part of the synthesis of glutamate, which is another nonessential amino acid.

Proline also supports cartilage synthesis to keep the proper functioning and structure of your joints. It’s a crucial amino acid for the elderly and those suffering from osteoarthritis.

Similar to others on this list of amino acids, Proline has antioxidant properties that protect body cells from damage.


Serine (Ser/S) is a hydroxylic amino acid involved in blood clotting and wound healing. It’s also involved in phospholipid synthesis that keeps the integrity of the body’s cell membranes.

Aside from that, Serine supports proper nervous system functions as part of dopamine and serotonin synthesis. These neurotransmitters regulate a person’s mood and behavior.

Serine is also part of creatine synthesis, which delivers energy to the muscles during intense exercise. It also supports various metabolic processes and takes part in the synthesis of other amino acids like cysteine and glycine.


Tyrosine (Tyr/Y) is an aromatic amino acid involved in the production of thyroid hormones that affect metabolism.

By speeding up your metabolism, tyrosine can aid in your weight loss journey. This is why it complements the benefits of our Weight Loss IV.

Aside from that, this amino acid is a precursor to several neurotransmitters like norepinephrine, epinephrine, and dopamine. All these chemicals affect a person’s mood, behavior, and overall mental performance.

Moreover, tyrpsine is also part of melanin synthesis. Melanin is the pigment that gives color to your hair, eyes, and skin.

What happens if you don't get enough amino acids?

Amino acid deficiency can lead to a slew of health problems. Whether it’s essential or nonessential types, any imbalance in these integral chemicals can lead to the following:

Muscle wasting. Since amino acids are the building blocks of protein, any deficiency can cause the muscles to waste away. This will make you physically weak and easily prone to fatigue.

Slow growth. Amino acid deficiency among kids and adolescents can cause delayed growth and development. This can contribute to stunting, poor mental performance, and poor overall health.

Hormonal imbalances. Many amino acids are precursors to hormone production. If you don’t have enough supply, it will trigger hormonal imbalances. This can throw off your body’s equilibrium and trigger a myriad of symptoms.

Hair and skin problems. A lack of amino acids will make your hair brittle and your skin prone to irritations. It’s because amino acids like cysteine and lysine are crucial to maintaining skin and hair health.

Impaired cognitive function. Amino acid deficiencies can lead to mood disorders, poor mental performance, and low motivation. This can lead to long-term adverse effects among children.

Anemia. Deficiency in certain amino acids, like histidine, can cause anemia. It’s because histidine boosts iron absorption, a crucial mineral in the creation of hemoglobin in the red blood cells.

Reduced athletic performance. Low levels of amino acids are equivalent to low protein synthesis in the body. And when you don’t have enough protein, your muscles will be too weak for strenuous activities like exercise or sports.
