Based on a gastrointestinal digestion model combined with a human intestinal cell culture, prunasin has been shown to be degraded into mandelonitrile by [beta]-glucosidase in the small intestine.
Prunasin, remaining in the gastrointestinal tract, can further be degraded into mandelonitrile by [beta]-glucosidase.
In Prunus, enzymes associated with this activity include amygdalin hydrolase, prunasin hydrolase, and mandelonitrile lyase (Swain et al.
In the body, the two sugar molecules are split off by the enzyme beta glucosidase (probably by bacteria in the colon) and are replaced by a glucuronic acid molecule to form a compound consisting of glucuronic acid bound to mandelonitrile (the benzaldehyde-cyanide radical).
