WebIn organic chemistry, thioesters are organosulfur compounds with the molecular structure R−C (=O)−S−R’. They are analogous to carboxylate esters ( R−C (=O)−O−R’) with the sulfur in the thioester replacing oxygen in the carboxylate ester, as implied by the thio- prefix. They are the product of esterification of a carboxylic acid ... WebA disulfide is a compound containing an -S-S- linkage.

Two tautomers are possible: a thione form (RC(S)OH) and a thiol form (RC(O)SH). These are sometimes also referred to as "carbothioic O-acid" and "carbothioic S-acid" respectively. Of these the thiol form is most common (e.g. thioacetic acid).
