  • S-Allyl-L-cysteine sulfoxide

Alliin is a cysteine sulfoxide constituent of garlic that is converted by alliinase to allicin, which imparts its pungent aroma and flavor.1,2 Alliin exhibits anti-cancer, anti-microbial, anti-hypertensive, cardioprotective, and anti-oxidant activities.3,4,5 S-allyl-cysteine is oxidized stereospecifically to (+)-alliin by garlic tissue cultures.2
