Hōʻike huahana:
Ua ʻike mua ʻia ka S-adenosylmethionine e nā kānaka ʻepekema (Cantoni) i ka makahiki 1952.
Hoʻohui ʻia ʻo ia e ka adenosine triphosphate (ATP) a me ka methionine i loko o nā pūnaewele e ka methionine adenosyl transferase (Methionine Adenosyl Transferase), a ke komo ʻo ia i ka hopena methyl transfer ma ke ʻano he coenzyme, nalowale ia i kahi hui methyl a decompose ia i loko o ka hui S-adenosyl Histidine. .
