S-Adenosyl L-methionine | 29908-03-0
Maelezo ya Bidhaa:
S-adenosylmethionine iligunduliwa kwa mara ya kwanza na wanasayansi (Cantoni) mnamo 1952.
Imeundwa na adenosine trifosfati (ATP) na methionine katika seli na methionine adenosyl transferase (Methionine Adenosyl Transferase), na inaposhiriki katika mmenyuko wa uhamishaji wa methyl kama koenzyme, hupoteza kikundi cha methyl na kuitenganisha katika kikundi cha S-adenosyl Histidine. .
