S-Adenosyl L-methionine |29908-03-0
Tuairisgeul toraidh:
Chaidh S-adenosylmethionine a lorg an toiseach le luchd-saidheans (Cantoni) ann an 1952.
Tha e air a cho-chur le adenosine triphosphate (ATP) agus methionine ann an ceallan le methionine adenosyl transferase (Methionine Adenosyl Transferase), agus nuair a bhios e a’ gabhail pàirt anns an ath-bhualadh gluasaid methyl mar coenzyme, bidh e a’ call buidheann methyl agus ga sgaoileadh a-steach do bhuidheann S-adenosyl Histidine. .
