S-Allyl cysteine (SAC) is an organic compound that is a natural constituent of fresh garlic. It is a derivative of the amino acid cysteine in which an allyl group has been added to the sulfur atom.

Allyl cysteine is currently being investigated as a potential cholesterol lowering agent and as a chemopreventive.
