L-Alanine
Alanine (Ala), also known as L-alanine is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. L-alanine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Alanine is found in all organisms ranging from bacteria to plants to animals. It is classified as an aliphatic, non-polar amino acid. In humans, alanine is a non-essential amino acid that can be easily made in the body from either the conversion of pyruvate or the breakdown of the dipeptides carnosine and anserine. Alanine can be also synthesized from branched chain amino acids such as valine, leucine, and isoleucine. Alanine is produced by reductive amination of pyruvate through a two-step process. In the first step, alpha-ketoglutarate, ammonia and NADH are converted by the enzyme known glutamate dehydrogenase to glutamate, NAD+ and water. In the second step, the amino group of the newly-formed glutamate is transferred to pyruvate by an aminotransferase enzyme, regenerating the alpha-ketoglutarate, and converting the pyruvate to alanine. The net result is that pyruvate and ammonia are converted to alanine. In mammals, alanine plays a key role in glucose–alanine cycle between tissues and liver. In muscle and other tissues that degrade amino acids for fuel, amino groups are collected in the form of glutamate by transamination. Glutamate can then transfer its amino group to pyruvate, a product of muscle glycolysis, through the action of alanine aminotransferase, forming alanine and alpha-ketoglutarate. The alanine enters the bloodstream and is transported to the liver. The alanine aminotransferase reaction takes place in reverse in the liver, where the regenerated pyruvate is used in gluconeogenesis, forming glucose which returns to the muscles through the circulation system. Alanine is highly concentrated in muscle and is one of the most important amino acids released by muscle, functioning as a major energy source. Plasma alanine is often decreased when the BCAA (branched-chain amino acids) are deficient. This finding may relate to muscle metabolism. Alanine is highly concentrated in meat products and other high-protein foods like wheat germ and cottage cheese. Alanine is an important participant as well as a regulator of glucose metabolism. Alanine levels parallel blood sugar levels in both diabetes and hypoglycemia, and alanine is reduced in both severe hypoglycemia and the ketosis of diabetes. Alanine is an important amino acid for lymphocyte reproduction and immunity. Alanine therapy has helped dissolve kidney stones in experimental animals. Normal alanine metabolism, like that of other amino acids, is highly dependent upon enzymes that contain vitamin B6. Alanine, like GABA, taurine, and glycine, is an inhibitory neurotransmitter in the brain (http://www.dcnutrition.com/AminoAcids/). L-Alanine. CAS Common Chemistry.

D-Alanine
Alanine is a nonessential amino acid made in the body from the conversion of the carbohydrate pyruvate or the breakdown of DNA and the dipeptides carnosine and anserine. It is highly concentrated in muscle and is one of the most important amino acids released by muscle, functioning as a major energy source. Plasma alanine is often decreased when the BCAA (Branched Chain Amino Acids) are deficient. This finding may relate to muscle metabolism.

Alanine, like GABA, taurine and glycine, is an inhibitory neurotransmitter in the brain. Alanine can be found in some Gram-positive bacteria (PMID:24752840). Amino acids are one of the most important molecules in living organisms, and most of them have a chiral carbon at a -position. In the higher animals, a large part of the naturally occurring amino acids is the L-form, and the stereoisomers (D-amino acids) had been believed to be rare. However, several D-amino acids have been found in mammals including humans, and their distributions, functions and origins have gradually been clarified. The D-alanine (D-Ala) amounts have also been reported to change in the case of diseases. Proteins of the frontal lobe white and gray matter of human brains, both normal and Alzheimer subjects, contain D-alanine at concentrations between 0.50 and 1.28 mumol/g of wet tissue, 50-70-times lower than the concentration of L-alanine. D-Alanine have been detected in the sera of both normal subjects and patients with renal dysfunction, and their concentrations were higher in the patients than in the normal subjects.
