L-allo-Isoleucine

CAS No. 1509-34-8

L-allo-Isoleucine ( (3R)-LS-Isoleucine;L(+)-Alloisoleucine )

Catalog No. M20000 CAS No. 1509-34-8

L-alloisoleucine is a branched chain amino acid and is a stereoisomer of L-isoleucine. It is a common constituent of human plasma (albeit at low levels). L-alloisoleucine is produced as a byproduct of isoleucine transamination. Plasma L-alloisoleucine which is derived from L-isoleucine in vivo can be used for the diagnosis of maple syrup urine disease (MSUD) a genetic disorder.

Plasma L-alloisoleucine which is derived from L-isoleucine in vivo can be used for the diagnosis of maple syrup urine disease (MSUD) a genetic disorder. Indeed plasma L-alloisoleucine levels above 5 μmol/L is the most specific and most sensitive diagnostic marker for all forms of MSUD.
