Fa'amatalaga o oloa:
S-adenosylmethionine na muamua maua e saienitisi (Cantoni) i le 1952.
O loʻo faʻapipiʻiina e le adenosine triphosphate (ATP) ma le methionine i sela e le methionine adenosyl transferase (Methionine Adenosyl Transferase), ma pe a auai i le methyl transfer reaction e avea o se coenzyme, e leiloa se vaega methyl ma pala i le vaega S-adenosyl Histidine. .
