S-Adenosyl L-methionine |29908-03-0
Whakaahuatanga Hua:
I kitea tuatahitia te S-adenosylmethionine e nga kaiputaiao (Cantoni) i te tau 1952.
Ka whakahiatohia e te adenosine triphosphate (ATP) me te methionine i roto i nga ruma e te methionine adenosyl transferase (Methionine Adenosyl Transferase), a, ka uru ki te tauhohenga whakawhiti methyl hei coenzyme, ka ngaro te roopu methyl, ka pirau ki te roopu S-adenosyl Histidine. .
