Threonine is one of two proteinogenic amino acids with two stereogenic centers, the other being isoleucine. Threonine can exist in four possible stereoisomers with the following configurations: (2S,3R), (2R,3S), (2S,3S) and (2R,3R). However, the name L-threonine is used for one single stereoisomer, (2S,3R)-2-amino-3-hydroxybutanoic acid. The second stereoisomer (2S,3S), which is rarely present in nature, is called L-allothreonine. The two stereoisomers (2R,3S)- and (2R,3R)-2-a… WebIn the case of amino acids with 2 chiral carbons such as threonine, there are four possible isomers, two of which are mirror images (enantiomers) and two of which are not (diasteriomers).
