WebAmino Acids Stereoisomers (amn) (gg3,mh5,sy2,vv2,zu4) Amino Acid Stereoisomers. Except for one AA, all standard AAs have an asymmetric or chiral α- carbon. Thus, stereochemical isomers exist for all but one of the standard amino acids. Structurally, stereoisomers are defined as non-superimposable chemical isomers that have identical … WebThreonine (Thr or T) ( (2S,31 ( )-2-amino-3- hydroxybutanoic acid) has an aliphatic hydroxyl side chain and is classified as a polar, uncharged amino acid with the formula HOOCCH (NH2)CHOHCH3. Together with Ser and Tyr, Thr is one of the three proteinogenic amino acids bearing an alcohol group. Thr can be seen as a hydroxylated version of Val.
