A major component of skunk spray, they tend to form strong complexes with heavy metal cations like arsenic and mercury, which led them to be called mercaptans.
This functional group can chelate with metals such as cadmium in ectomycorrhizal fungi to increase metal tolerance. One of these will be created by treating a carbonyl compound with Lawesson's reagent and then reducing, and the Barton-Kellogg reaction uses the ketone variety of them to synthesize olefins. Aqueous work-up following the Herz reaction places one of them on an aromatic ring, as does the Leuckart reaction. They can be oxidized with agents like bromine, and compounds which interfere with that process are often used to denature proteins.

FTP, name this functional group which consists of a sulfur atom bonded to a hydrogen atom.
