Mercapturates acid - organic acetylated derivatives of cysteine.
Soluble in hot water, alcohol, insoluble in ether; optically active, restore Fehling's solution, with hydroxide barium give insoluble salt.
Reaction deposition mercapturic acids mercury is used for their quantitative values of determination.
Mercapturates acid found in the urine of animals and humans in the introduction to their body halogenated aromatic compounds.
