Mafotokozedwe Akatundu:
S-adenosylmethionine idapezeka koyamba ndi asayansi (Cantoni) mu 1952.
Imapangidwa ndi adenosine triphosphate (ATP) ndi methionine m'maselo ndi methionine adenosyl transferase (Methionine Adenosyl Transferase), ndipo ikatenga nawo gawo pakusintha kwa methyl monga coenzyme, imataya gulu la methyl ndikuliwola kukhala gulu la S-adenosyl Histidine. .
