Biochem/physiol Actions
Sulfur-containing amino acid that is converted to allicin by alliinase. Allicin is cytotoxic to several mammalian cancer cell lines and can protect against tumor formation induced by various exogenous chemical carcinogens.
L-Alliin (S-Allyl-L-cysteine sulfoxide) is an amino acid derived from L-cysteine. S-Allyl-L-cysteine Sulfoxide (ACSO) is an anti-atherosclerotic compound with antioxidant and anti-inflammatory activities.
S-Allyl-L-cysteine ((±)-L-Alliin) (SAC) may be used to study its potential as an anti-Alzheimer’s factor. SAC has been shown to increase cell proliferation and neuroblast differentiation by increasing 5-HT(1A) and provide antioxidative benefit to neurons and synapses.
