Metabolite Identification
Common Name(S)-4-Hydroxymandelonitrile
Description(S)-4-Hydroxymandelonitrile belongs to the class of organic compounds known as 1-hydroxy-2-unsubstituted benzenoids. These are phenols that are unsubstituted at the 2-position (S)-4-Hydroxymandelonitrile is an extremely weak basic (essentially neutral) compound (based on its pKa) (S)-4-Hydroxymandelonitrile exists in all living organisms, ranging from bacteria to humans. Outside of the human body, (S)-4-Hydroxymandelonitrile has been detected, but not quantified in, several different foods, such as common thymes, grapefruit/pummelo hybrids, celeriacs, nopals, and apples. This could make (S)-4-hydroxymandelonitrile a potential biomarker for the consumption of these foods. A 4-hydroxymandelonitrile that has (S)-configuration.

Enzymes

General function:
Involved in hydrolase activity, hydrolyzing O-glycosyl compounds
Specific function:
Glycosidase probably involved in the intestinal absorption and metabolism of dietary flavonoid glycosides. Able to hydrolyze a broad variety of glycosides including phytoestrogens, flavonols, flavones, flavanones and cyanogens. Possesses beta-glycosylceramidase activity and may be involved in a nonlysosomal catabolic pathway of glycosylceramide.
