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.[4]
L-Alanine accounts for 7.8% of the primary structure in a sample of 1,150 proteins.[5][6] Leucine is the only amino acid which is more common.
D-Alanine occurs in bacterial cell walls and in some peptide antibiotics.
