Description and Uses

Alliin (S-allyl cysteine sulfoxide) is an organic sulfur-containing product derived from the amino acid cysteine. It is the precursor of thiosulfinates, which are responsible for the characteristic pungent flavours of Allium species. It is an L-alanine derivative in which one of the methyl hydrogens of L-alanine has been replaced by an (S)-allyl sulfinyl group. It has a role as a plant metabolite, an antioxidant, a cardioprotective agent, a neuroprotective agent and an antimicrobial agent. It is a non-proteinogenic alpha-amino acid, an L-cysteine derivative, an L-alanine derivative, a sulfoxide and an olefinic compound. It is a tautomer of an alliin zwitterion.
