S-Allyl-L-cysteine is a sulfur-containing, proteinogenic amino acid derivative featuring the cysteine backbone with an S-allyl thioether substituent on the side-chain thiol, retaining the L-configuration at the alpha carbon. The molecule contains a free amino group and a free carboxyl group, while the side-chain sulfur is present as a thioether (not a free thiol), which alters nucleophilicity and provides a hydrophobic allyl handle for further chemical modification. In biochemical and synthetic workflows, it is used as a cysteine analog for preparing thioether-functionalized peptides and conjugates, as a substrate or reference material in chemical biology studies involving sulfur chemistry, and as a labeled or modifiable building block for generating more complex amino acid derivatives.
