L-isoleucine Powder CAS 73-32-5

Isoleucine is one of the twenty basic amino acids that are present in the structure of almost all proteins. Its chemical composition is identical to that of leucine, but the order of atomic linkage/arrangement is different, and thus it has different properties from leucine. Isoleucine is a hydrophobic amino acid. Isoleucine has two para-palmitic centers, so there are four stereoisomers and two diastereomers of L-isoleucine. But in any case, there is only one type of naturally occurring isoleucine, namely L-isoleucine
