Thiolysis

Thiolysis is a chemical reaction where a thiol (R-SH) helps break one molecule into two parts. In some cases, coenzyme A is added to one of the products. It is similar to hydrolysis, which uses water to break bonds. Thiolysis occurs in fatty acid β-oxidation in cells. The term also describes the breakdown of condensed tannins when benzyl mercaptan acts as the nucleophile.
