S-Adenosyl-L-homocysteine (SAH) is an amino acid derivative used in several metabolic pathways in most organisms. It is an intermediate in the synthesis of cysteine and adenosine.^[1]

SAH is formed by the demethylation of S-adenosyl-L-methionine and is converted to homocysteine and adenosine by adenosylhomocysteinase.
