Glucosinolates

Glucosinolates, or mustard oil glycosides, are like the cyanogenic glycosides, non-toxic substances which give toxins after the enzymic cleavage of the glycoside. About 100 of them are known, and some have been found in all species of Cruciferae examined. Their synthesis in the plant begins with N-hydroxylation of an amino-acid or modified amino-acid and decarboxylation. Further steps are not known with certainty, but probably proceed as shown in Figure 10.12.
