Alanine (abbreviated as Ala or A) is an -amino acid with the chemical formula CH3CH(NH2)COOH. The L-isomer is one of the 20 proteinogenic amino acids, i.e. the building blocks of proteins. Its codons are GCU, GCC, GCA, and GCG. It is classified as a nonpolar amino acid. L-alanine is second only to leucine, accounting for 7.8% of the primary structure in a sample of 1,150 proteins. D-alanine occurs in bacterial cell walls and in some peptide antibiotics.
In medicine,High optical purity of L-Alanine is an important chiral source used in synthesis of many types of drugs. And it is raw material to compose amino acid injection and oral liquid.
 In food industry, l-alanine is added in chemistry seasoning, drinks, organic acid, wine and salted food. As one important additive, l-alanine has the fuction of keeping fresh.
Descriptions:White crystal or crystalline powder with special sweet taste, easily dissolves in water.,sparingly soluble in ethanol,and insoluble in ether.
