- Metabolic products:
- * Cystine, a cysteine dimer, and an oxidation product of cysteine
- * Homocysteine
- * Homocystine, a homocysteine dimer, and an oxidation product of homocysteine
- * Cystathionine, produced by the transsulfuration pathway
- * S-Adenosyl methionine, a common cofactor in methyltransferases
- * S-Adenosyl homocysteine, a side product of biomethylation by methyltransferases
