Alanine (abbreviated as Ala or A) is an alpha-amino acid with the chemical formula CH3CH(NH2)COOH. The L-isomer is one of the 22 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 in rate of occurrence, 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. L-Alanine is found in many foods, some of which are snow crab, persian lime, papaya, and jerusalem artichoke. |
