The chemical syntheses of human metabolites of S‐carboxymethyl‐L‐cysteine (3) and S‐methyl‐L‐cysteine (12) are described. The additional preparation of some 2H‐ and 13C‐labelled isotopomers enabled the direct evaluation of the stabilities of 3 and 12 under physiological conditions and also facilitated the unambiguous assignments of the signals in the 13C‐NMR spectra of all compounds mentioned.
