What is Amino Acid?
Amino acids, often referred to as the building blocks of proteins, are compounds that play many critical roles in your body. You need them for vital processes such as building proteins, hormones, and neurotransmitters. Amino acids are concentrated in protein-rich foods such as meat, fish, and soybeans. Some people also take certain amino acids in supplement form as a natural way to boost athletic performance or improve mood.
Health Benefits of Amino Acids
Providing the body with energy
Isoleucine and valine, in particular, are good sources of energy to fuel the body.
Enhancing the musculoskeletal system
Isoleucine and valine assist with healthy muscle function, while leucine works to repair muscles. Lysine promotes calcium absorption needed for bone growth. These amino acids are good for healthy, toned muscles and strong bones. Isoleucine and valine are common ingredients in workout supplements because they target the muscles and boost energy.
Regulating digestion
Your body produces histamine to help your digestive system work properly. You need histamine to histidine to help generate histamine.
Enforcing healthy sleep/wake cycles
Erratic sleep habits caused by issues such as insomnia, sleep apnea, and stress, can take a toll on your overall health. Histidine and tryptophan help you maintain normal circadian rhythms for a good night’s sleep.
Supporting the immune system
Want to keep colds and flu at bay? histidine, lysine, and threonine help boost immunity so your body can better fight off viruses.
Producing neurotransmitters
These chemicals are the nervous system’s way of communicating with the body, regulating everything from appetite to mood. Phenylalanine not only produces some neurotransmitters but other types of amino acids, too.
Stimulating the growth of healthy skin, nails, and hair
Collagen and elastin keep your complexion looking soft and supple. These two proteins also encourage hair and nail growth. Lysine assists with collagen production, while threonine helps generate collagen and elastin.
Producing hormones
Amino acids such as lysine are useful for maintaining healthy hormone levels. Examples of amino acid hormones include epinephrine and norepinephrine, which oversee the body’s stress response, and thyroxine, which plays a role in metabolism.
Maintaining a healthy weight
Methionine governs our metabolic rate and can also help with detoxification, while threonine is key for metabolizing fat.
Balancing your moods
Tryptophan jump-starts the production of serotonin, a hormone that’s essential for feeling happy and well-adjusted.
Types of Amino Acid
Nonessential Amino Acids
These types of amino acids are produced naturally by your body and have nothing to do with the food you eat.
The following are examples of nonessential amino acids:
● Alanine
● Asparagine
● Aspartic acid
● Glutamic acid
Essential Amino Acids
These types of amino acids can’t be produced by the body and must come from the food you eat.
If you don’t eat foods that contain essential amino acids, your body won’t have them. The following are essential amino acids:
● Histidine
● Isoleucine
● Leucine
● Lysine
● Methionine
● Phenylalanine
● Threonine
● Tryptophan
● Valine
It isn’t necessary to eat essential amino acids at every meal. You can get healthy amounts by eating foods containing them throughout the day.
Animal-based foods such as meat, dairy, poultry, fish, and eggs provide essential amino acids.
Conditional Amino Acids
These types of amino acids are usually not essential to everyday living but are important when you’re sick, injured, or stressed.
Conditional amino acids include:
● Arginine
● Cysteine
● Glutamine
● Tyrosine
● Glycine
● Ornithine
● Proline
● Serine
When you’re ill or injured, your body may not be able to produce enough conditional amino acids, and you may need to give your body what it needs through diet or supplements.
Application of Amino Acid
Active Pharmaceutical Ingredients (APIs)
There are pharmaceutical products that make use of amino acids themselves, and products that are synthesized and manufactured using amino acids as starting materials. Amino Acids are also used in infusion solutions, in addition to tablet and granulated forms, and are an essential part of modern medical treatments.
Medical Foods / Medical Nutrition
Amino Acids are used as a way to provide a concentrated, specific and efficient intake of required nutrient components in medical foods for malnourished patients, elderly people with lower digestive capabilities, as well as in other uses.
Dietary Supplement / Health Foods / Functional Foods & Beverages
Amino Acids are used for compensating amino acid deficiencies, as well as in supplements that make use of the specific function of amino acids. Products are sold in tablet, granular and capsule forms. These products were once mostly used by athletes, but they are now popular among the wider public for everyday workout and health maintenance. There are also functional food and beverage products that contain amino acids for functions similar to those found in health foods.
Cosmetics
Amino Acids are used in cosmetics for their unique moisturizing effect and pH levels. Amino acid derivatives are also used for their stability and absorbency.
Culture Medium
Recently, pharmaceutical products research and manufacture using cell culture process have become very popular. Amino Acids are essential components of cell culture medium. Amino Acids are considered to be indispensable to cell growth and production of antibodies and proteins.
Quinoa
Quinoa is one of the most nutritious grains available today. In addition to being a good source of fiber, it contains all nine essential amino acids that your body needs from food. It also has a higher amount of lysine than wheat or rice, making it a better source of these amino acids than other grains.
Eggs
Eggs are an excellent source of protein, containing all of the essential amino acids. Studies suggest that the amino acids provided by eggs are better utilized by your body than other sources like casein or soy.
Turkey
Turkey has high amounts of tryptophan, an amino acid the body uses to make the B vitamin called niacin, which is necessary for digestion, healthy skin, and nerves. Tryptophan also helps produce serotonin, which affects your mood and can contribute to feelings of happiness and relaxation. Because they’re all high in protein, other meats are good sources of amino acids as well.
Cottage cheese
One 100-gram serving of cottage cheese provides about 25% of your daily value of protein and contains significant quantities of several amino acids, including threonine and tryptophan.
Mushrooms
Mushrooms contain a total of 17 amino acids, including all of the essential ones. One study showed that supplementing a cereal diet with mushroom would help overcome lysine deficiency.
Fish
Most types of fish contain essential amino acids and other important micronutrients. Salmon is high in amino acids and Omega 3s (important fatty acids that support heart and other health).
Legumes and Beans
Legumes are a great source of high-quality protein — 20-45% of their protein is rich in the amino acid lysine. Peas and beans contain 17-20% high-quality protein while lupins and soybeans contain 38-45%.
An amino acid is an organic chemical. Organic chemicals contain carbon-hydrogen bonds. All amino acids have the same basic structure. Each molecule has a central carbon atom linked together with a basic amino group, a carboxylic acid group, a hydrogen atom and an R-group, or side-chain group. The R-group is what sets the amino acids apart. The R-group determines each amino acid’s chemical nature. The chemical nature controls how it’ll interact with other amino acids and its environment. The amino acids link together with peptide bonds and become proteins. Then, the forces of other amino acids and the effects of their R-groups fold the protein into specific three-dimensional shapes.

There are many important purposes of amino acids, so it’s crucial to get enough of them. The good news is that it’s typically easy to get adequate amounts of the essential amino acids if you regularly eat a healthy diet. However, deficiencies, while uncommon, can occur as a result of poor eating habits or medical conditions that interrupt amino acid absorption in the body. Signs of a deficiency include thinning hair, skin sores, edemas and loss of muscle mass.
Best Sources of Amino Acids
Pros: Essential amino acids are found in a wide variety of foods: meat, dairy, quinoa, salmon, leafy green vegetables, legumes and potatoes, to name a few.
Cons: It can be hard to change unhealthy eating habits, and busy people may find it difficult to plan, shop for and prepare nutritious meals.
Pros: Supplements are a convenient way for people to get the amino acids they can’t consume in their diet. There are several different kinds of supplements to choose from, such as protein powders or pills, and they can be relatively affordable.
Cons: Oral supplements lose some of their potency because they have to pass through the digestive system. Medications or health issues also may prevent effective absorption. And you’ll have to do some homework to make sure you purchase a supplement of high quality.
Pros: Compared to oral supplements, IV therapy delivers amino acids right to the bloodstream. That means they’re rapidly absorbed into the body for potent, immediate effect and usually work faster than oral supplements. Mobile service provides treatment at your home or office for extra comfort.
Cons: It takes longer (about 45 to 60 minutes for a full session) to get IV treatment than to consume an oral supplement (Though IV treatment does deliver vitamins more quickly to your bloodstream). IV treatment is also the most expensive option, and there is a slight chance of infection where the IV is inserted into your skin.
How Amino Acids are Made
Fermentation is a natural process
In amino acid fermentation, amino acids are made by fermenting ingredients with a culture medium containing microorganisms such as probiotic bacteria. These microorganisms turn the ingredients into food and other substances that they need. An ingredient such as molasses is also added to are added to help the microorganisms multiply and make amino acids. The Microorganisms contain enzymes that accelerate the reactions involved in breaking down ingredients and synthesizing new substances. The fermentation process is a series of reactions involving between 10 and 30 different enzymes.
Other ways to make amino acids
In addition to fermentation, there are other ways to make amino acids, such as enzymatic reaction, extraction and synthesis.
In the enzymatic reaction process, one or two enzymes are used to turn an amino acid precursor into the right amino acid. In this method there is no need to multiply microorganisms by converting the specific amino acid, and there is no long process starting from glucose. The enzymatic reaction process is ideal if the precursor substance has a low cost.
Amino acids can be produced by breaking down proteins. This is known as the extraction method. However, the quantity of amino acids in the source protein limits the quantity of amino acids that can be produced, so this method is unsuitable for making mass quantities of specific amino acids.
The synthesis method uses chemical reactions to make amino acids, and was widely used in the early development of amino acids production techniques. The problem with this method is that chemical reactions make equal amounts of L- and D-amino acids, so a the D-amino acids must then be converted into L-amino acids. Requiring extra processing steps and equipment, this method was more expensive, and was therefore gradually phased out. However, it is still used to make glycine, which does not occur in D- and L- forms, and for amino acids that are equally useful in either D- or L- forms.
