Amino Acids Amino Acids Organic compounds that generally contain an amino (-NH2) and a carboxyl (-COOH) group. Twenty alpha-amino acids are the subunits which are polymerized to form proteins. Amino acidAbbr.Amino acidAbbr. Alanine Ala,A Leucine Leu,L Arginine Arg,R , ,
Branched-chain amino acids (BCAA) Branched-chain amino acids (BCAA) Branched-chain amino acids consist of isoleucine, leucine and valine that have branched-side chain. Since the BCAAs are abundantly found in skeletal muscle, they are often used for a supplement food. Isoleucine <jmol ile.pdb.gz 150 150></jmol> Leucine , , ,
