| 3.2.1.118 | prunasin + H2O |
prunasin is taken up in the small intestine and decomposed by beta-glucosidase into glucose and mandelonitrile, which is further hydrolyzed to benzaldehyde and hydrogen cyanide. Amygdalin, the precursor of prunasin, is a toxic component and can cause fatal cyanide poisonings, chronic toxicity, and death |
