Myrosinase is a thioglucohydrolase located apart from glucosinolates in so-called myrosin cells.
In fact, papaya seeds contain several molecules, like fatty acids, crude protein, crude fiber, papaya oil, carpaine, benzyl isothiocyanate, glucotropaeolin, benzyl thiourea, hentriacontane, [beta]-sitosterol, caricin, and an enzyme myrosin [7] that confer vermifuge [25, 26], abortifacient [27, 28], antifertility [29-32], wound-healing [33], anticancer [34], antibacterial [35], and antifungal [36] properties as well as antioxidant activities for the presence of secondary metabolites, such as phenolic compounds, vanillic acid, flavonoids, a-tocopherol, and vitamin C.
Mustard's alluring pungency only develops when cold water is blended with the ground seed and a reaction occurs between the enzyme myrosin and the glycoside sinigrin, resulting in a sulfurous compound captured in the highly volatile (and hot-tasting) seed oil.
stated that Pawpaw (Carica papaya) seeds yield 660-760mg (bactericidal a glycone of glucotropaeolin benzyl isothiocyanate), a glycoside, sinigrin, the enzyme myrosin, and carpasemine.
