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. (±)-Alanine is found in many foods, some of which are green bell pepper, red bell pepper, green zucchini, and italian sweet red pepper.

Alanine and derivatives are compounds containing alanine or a derivative thereof resulting from reaction of alanine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom.
