Metabolite Identification
Common Name(2R)-2-Hydroxy-2-methylbutanenitrile
Description(2R)-2-Hydroxy-2-methylbutanenitrile, also known as (2R)-2-hydroxy-2-cyanobutane or (R)-butan-2-one cyanohydrin, belongs to the class of organic compounds known as tertiary alcohols. Tertiary alcohols are compounds in which a hydroxy group, -OH, is attached to a saturated carbon atom R3COH (R not H ) (2R)-2-Hydroxy-2-methylbutanenitrile is an extremely weak basic (essentially neutral) compound (based on its pKa) (2R)-2-Hydroxy-2-methylbutanenitrile exists in all living organisms, ranging from bacteria to humans. Outside of the human body, (2R)-2-Hydroxy-2-methylbutanenitrile has been detected, but not quantified in, several different foods, such as okra, beans, rocket salad, garden onions, and cabbages. This could make (2R)-2-hydroxy-2-methylbutanenitrile a potential biomarker for the consumption of these foods. These are compounds in which a hydroxy group, -OH, is attached to a saturated carbon atom R3COH (R ≠ H ).

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.
