Phenethyl isothiocyanate (PEITC) is a naturally occurring
isothiocyanate In organic chemistry, isothiocyanate is a functional group as found in compounds with the formula . Isothiocyanates are the more common isomers of thiocyanates, which have the formula . Occurrence Many isothiocyanates from plants are produce ...
whose precursor, gluconasturtiin is found in some cruciferous vegetables, especially watercress. PEITC has been studied for its potential for chemoprevention of cancers, such as prostate cancer. In terms of
biosynthesis Biosynthesis, i.e., chemical synthesis occurring in biological contexts, is a term most often referring to multi-step, enzyme-Catalysis, catalyzed processes where chemical substances absorbed as nutrients (or previously converted through biosynthe ...
, PEITC is produced from gluconasturtiin by the action of the enzyme myrosinase.
