L-Alanine- As one of the twenty alpha amino acids that are proteinogenic, which means that these amino acids are building blocks of proteins, L-Alanine is the second most abundant amino acid, with leucine being the first. This nonpolar amino acid can be produced by the body by means of reductive amination of pyruvate and some branched chain amino acids, like isoleucine, leucine and valine. Liver and tissues depend on alanine, which plays a prominent role in the glucose alanine cycle. Alanine is also involved in the removal of nitrogen from tissues to the liver, but alanine also assists in the blood sugar tapping of the body for energy requirements. Despite being a non-essential amino acid, alanine is found in meat, dairy products, fish, poultry, eggs, some beans, nuts and seeds, brown rice bran, corn and whole grains, among other sources.

L-Aspartic Acid is a proteinogenic alpha amino acid, one of the twenty that are deemed the building blocks of proteins. L-Aspartic Acid is considered non-essential, because the human body can produce it from the organic compound oxaloacetate through a process called transamination. Despite L-Aspartic Acid being classified as non-essential, it is available through dietary sources such as luncheon meats, wild game meat, sausage meat, oat flakes, avocadoes, asparagus and various sprouting seeds. L-Aspartic Acid is also playing a role in the removal of ammonia, but also as a precursor and in the production and synthesis of various biochemical compounds such as arginine, isoleucine, threonine, asparagine, lysine and some nucleotides. In recent years studies have revealed that L-Aspartic Acid seems to raise the body’s resistance to fatigue, thereby boosting endurance.

L-Glutamine- Found in plasma and muscles of the human body, L-Glutamine is an essential amino acid. In the skeletal muscle cells, more than 60% of free floating amino acid is made of L-Glutamine. It acts as the primary donor of nitrogen and moves in the body wherever required. This amino acid has been considered useful in reducing physical stress. During surgery or heavy exercise regime the human body needs it for maintaining the level of glutamine in muscles and blood. It is also essential for maintenance of immune system and prevention of intestinal stress. Glutamine supplements can help in restoring L-Glutamine levels during stress. L-Glutamine supplements are relatively less expensive and help in minimizing the breakdown of muscles. It also improves the metabolism of protein in the human body and ensures a positive balance of nitrogen.

L-Glycine- Glycine is an organic compound and one of the 20 amino acids deemed as building blocks for proteins. This proteinogenic amino acid is not only the smallest but also the only amino acid of the group that is not chiral, which means there is no enantiomer of glycine. With the prominent exception of collagen, which thirty five percent are glycine, most proteins contain only small amounts of it. As a solid, glycine is sweet tasting, crystalline and has no color. Despite being non-essential, because it can be biosynthesized from the amino acid serine, glycine has several important physiological functions, besides being a precursor to proteins. It is a biosynthetic intermediate of purines and the D-Aminolevulinic acid and it is an inhibitory neurotransmitter found in the central nervous system.

L-Isoleucine- The second of three branched chain amino acids it is important in blood sugar regulation and producing hemoglobin. After exercise, it is responsible for muscle recovery and important in the metabolism to produce energy.

You can also find L-Methionine in vegetables and fruits. Since it is a glycogenic amino acid, it helps in forming glycogen and D-glucose. On a daily basis, experts recommend only 13 mg of L-Methionine for adults. These supplements are not only effective in liver disease treatment but also beneficial for individuals who follow a vegetarian diet. You can enhance the quality of your skin, hair and nails by taking L-Methionine supplements.

L-Phenylalanine gained notoriety with the aspartame controversy where extensive internet bombardment against the artificial sweetener prompted a thorough cleaning by The Coca Cola Company and other interest groups. Now it seems that aspartame has more benefits to health than aspirin. L-Phenylalanine is an essential alpha amino acid that is deemed analgesic and antidepressant. It is hydrophobic and nonpolar, one of only twenty common amino acids that are used to produce protein as coded by the DNA. L-Phenylalanine can also convert into L-Tyrosine, which can then become L-DOPA, going forth to become norepinephrine, dopamine or epinephrine. Phenylalanine is very often found in foods, protein rich foods like meat, milk and milk products, poultry and fish, but also as already mentioned in the artificial sweetener aspartame.

L-Proline is a proteinogenic alpha amino acid, one of only twenty amino acids that are DNA encoded for the forming of protein. It is not deemed essential because humans are able to synthesize it from the amino acid L-Glutamate. This unique member of the twenty protein building block amino acids is the only one of the group that is distinct as belonging to the secondary alpha amino group. L-Proline plays a role in the synthesis of collagen. Collagen is undeniably the most common protein in mammals, being found in skin, tendons, joints, ligaments, vasculature and bones. It is deemed good for the health of joints, when taken as a supplement. Low protein diets, vegetarian and vegan diets as well as malnutrition lead to diminished L-Proline levels.

L-Serine- Serine is an organic compound and a proteinogenic amino acid that is considered a building block for the creation of proteins. This member of the hydroxyl group and a polar amino acid is not essential and therefore it is not necessary to ingest it by means of diet. L-Serine can be synthesized from metabolites such as glycine. L-Serine plays a role in the biosynthesis of pyrimidines and purines, furthermore it is a precursor to many metabolites like sphingolipids and to amino acids like cysteine and glycine. It is also involved in catalytic functions of several enzymes. L-Serine can be transformed into D-Serine by the serine racemase, which functions as a neuronal signal and NMDA receptor activator in the brain, a vital glutamate receptor responsible for memory functions and synaptic plasticity.

L-Threonine is an amino acid that is essential to the body, but must be obtained from various sources, as it is not produced by the body. L-Threonine is a well known amino detoxifying agent which works in the liver, preventing the build up of fat. It assists in metabolism and helps the intestinal and digestive tracts to function with absolute ease. L-Threonine also helps in the formation of enamel, elastin, collagen and muscle tissue. Foods rich in Threonine are leafy vegetables, poultry and pork, but it can be obtained from various pulses, whole grains, nuts and fruits like peaches and pairs. Commonly used in the relief of stress and anxiety, L-Threonine helps the consumer to have a completely healthy mental and physical style of living.

L-Tyrosine is a proteinogenic polar amino acid, deemed not essential because it can be synthesized by the human body. As a member of the amino acid group that is being used by cells to build proteins, this building block derived its name from the Greek word tyros, which means cheese, because it was discovered in the cheese protein casein. L-Tyrosine can be synthesized from phenylalanine and can be found in foods high on protein, like soy products, poultry, cheese, bananas, dairy products and several seeds, including the sesame seeds. The unique phenol functionality and the occurrence in proteins that belong to the signal transduction process, make this amino acid different. Tyrosine can be converted by tyrosine hydroxylase enzyme into levodopa, a psychoactive drug that is used, among other uses, for clinical treatment of Parkinson’s disease. It is also involved in the synthesis of dopamine, norepinephrine and epinephrine.

L-Valine is an essential alpha amino acid and one of the three essential branched chain amino acids found in the human body. The other two essential BCAAs are leucine and isoleucine. The name is derived from the plant valerian. Valine is also classified as nonpolar and is known by sickle cell disease sufferers as the substitute amino acid for the glutamic acid, whereby the hydrophobic qualities of valine cause the hemoglobin to not fold correctly. Just like the other three BCAAs, the primary source of valine is through ingestion of proteins, where valine is a component; some such sources would be fish, peanuts, poultry, cottage cheese, lentils and sesame seeds. L-Valine is found in large quantities in muscles, whereby in the muscle metabolism it is essential for the restoration and tissue growth.
