S-Adenosyl L-metionin | 29908-03-0
Deskripsi Produk:
S-adenosylmethionine pisanan ditemokake dening ilmuwan (Cantoni) ing taun 1952.
Iki disintesis dening adenosin trifosfat (ATP) lan metionin ing sel dening methionine adenosyl transferase (Methionine Adenosyl Transferase), lan nalika melu reaksi transfer metil minangka koenzim, gugus metil ilang lan decomposes dadi histidine gugus S-adenosyl. .
