Metabolism of Homocysteine. The metabolism of methionine is depicted only till the formation of cysteine. Homocysteine can be either remethylated to methionine (Remethylation pathway) or can be routed for the formation of cysteine (Transsulfuration pathway). Cys- Cysteine, Gly- Glycine, Hcy- Homocysteine, HTL- Homocysteine thiolactone, SAH- S-adenosyl-L-homocysteine, SAM- S-adenosyl-L-methionine, THF- Tetrahydrofolate, CH2THF- Methylene tetrahydrofolate, CH3THF- Methyl tetrahydrofolate, Met- Methionine, Ser- Serine, α-KB- α-ketobutyrate, MTHFR- Methylene tetrahydrofolate reductase, CβS- Cystathionine β synthase, CSE- Cystathionine γ lyase, SAHH- S-adenosyl homocysteine hydrolase
