Alanine (abbreviated as Ala or A) is an α-amino acid. It has the chemical formula CH3CH(NH2)COOH.
The L-isomer is one of the 20 amino acids encoded by the genetic code. Its codons are GCU, GCC, GCA, and GCG. It is classified as a non-polar amino acid.
L-Alanine accounts for 7.8% of the primary structure in a sample of 1,150 proteins. Leucine is the only amino acid which is more common.
D-Alanine occurs in bacterial cell walls and in some peptide antibiotics.
