Isoleucine is one of the 20 natural amino acids, and is coded for in DNA. Its chemical composition is identical to that of leucine, but the arrangement of its atoms is slightly different, resulting in different properties. Nutritionally, in humans, isoleucine is an essential amino acid.
Isoleucine has two chiral centers; therefore there are four possible stereoisomers of isoleucine and two possible diastereomers of L-isoleucine. However, isoleucine present in nature exists in one enantiomeric form, (2S,3S)-2-amino-3-methylpentanoic acid.External links
