prunasinn.

Brit.

/ˈpruːneɪsn/,

/ˈpruːnəsɪn/, U.S.

/ˈprunəs(ə)n/

Origin: Formed within English, by derivation. Etymons: prunase n., -in suffix¹.

Etymology: < prunase n. + -in suffix¹.

A crystalline, cyanogenic glycoside related to amygdalin, found in a number of trees (notably the bird cherry, Prunus padus).Prunasin is the racemic form of a glucoside of the nitrile of mandelic acid. Formula: C₆H₅·CH(CN)·OC₆H₁₁O₅.

1988 New Scientist 31 Mar. 29/2 These leaves are rich in prunasin, a compound that breaks down during digestion to release cyanide and benzaldehyde.
