Deskripsyon pwodwi:
S-adenosylmethionine te premye dekouvri pa syantis (Cantoni) an 1952.
Li se sentèz pa adenosine trifosfat (ATP) ak methionine nan selil pa methionine adenosyl transferase (Methionine Adenosyl transferase), epi lè li patisipe nan reyaksyon an transfè methyl kòm yon coenzyme, li pèdi yon gwoup methyl epi dekonpoze li nan gwoup S-adenosyl Histidine. .
