- Cysteine (Cys, C)
- Methionine (Met or M), an essential amino acid in humans
- Metabolic products:
- Cystine, a cysteine dimer, and an oxidation product of cysteine
- Homocysteine (Hcy)
- Homocystine, a homocysteine dimer, and an oxidation product of homocysteine
- Cystathionine, produced by the transsulfuration pathway
- S-Adenosyl methionine (SAM, SAMe, SAM-e, AdoMet), a common cofactor in methyltransferases
- S-Adenosyl homocysteine (SAH), a side product of biomethylation by methyltransferases
