Chemical Information
FooDB Name(±)-Alanine
DescriptionDietary supplement, nutrient, sweetening flavour enhancer in pickling spice mixts. 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.
