L-ALLO-ISOLEUCINE Chemical Properties,Usage,Production

Chemical Properties

White to off-white powder

Uses

L-alloisoleucine is a stereo-isomer of L-isoleucine (I820175) and is produced as a byproduct of isoleucine via transamination.? L-allo-isoleucine has been suggested to induce epithelial β-defensin expression. In addition, L-allo-isoleucine is utilized in the biosynthesis pathway for coronamic acid.

Definition

ChEBI: L-alloisoleucine is an optically active form of alloisoleucine having L-(2S,3R)-configuration. It has a role as a human metabolite. It is a non-proteinogenic L-alpha-amino acid and an alloisoleucine. It is an enantiomer of a D-alloisoleucine. It is a tautomer of a L-alloisoleucine zwitterion.

Biochem/physiol Actions

L-allo-Isoleucine may be used in studies on maple syrup urine disease.
