carbocysteine	An L-cysteine thioether that is L-cysteine in which the hydrogen of the thiol group has been replaced by a carboxymethyl group.	S-carboxymethyl-L-cysteine
cysteine tryptophylquinone	An L-tryptophan derivative that is L-tryptophan-6,7-dione in which a cysteine unit is attached at position 4 via its side-chain thiol group.	cysteine tryptophylquinone
felinine	A cysteine thioether that is the S-(4-hydroxy-2-methylbutan-2-yl) derivative of L-cysteine. It is a major component of the urine of the domestic cat.	felinine zwitterion; felinine
lanthiopeptin	A type B lantibiotic consisting of a 19 amino acid tetracyclic polypeptide produced by Streptomyces cinnamoneus.	cinnamycin
leukotriene e4	A leukotriene that is (7E,9E,11Z,14Z)-icosa-7,9,11,14-tetraenoic acid substituted by a hydroxy group at position 5 (5S) and an L-cystein-S-yl group at position 6 (6R).	leukotriene E4
s-(1,2-dicarboxyethyl)cysteine	An L-cysteine thioether that is L-cysteine in which the hydrogen of the thiol group has been replaced by a 1,2-dicarboxyethyl group. It is a chemical modification which occurs in tissue proteins and formed by a Michael addition of cysteine to fumaric acid.	S-(2-succinyl)-L-cysteine
s-2-aminoethyl cysteine	A cysteine derivative that is the S-(2-aminoethyl) analogue of L-cysteine; reported to have cytotoxic effects.	L-thialysine
