S-Adenosyl L-methionine |29908-03-0, ib
Product Description:
S-adenosylmethionine tau pom thawj zaug los ntawm cov kws tshawb fawb (Cantoni) hauv xyoo 1952.
Nws yog tsim los ntawm adenosine triphosphate (ATP) thiab methionine hauv hlwb los ntawm methionine adenosyl transferase (Methionine Adenosyl Transferase), thiab thaum nws koom nrog cov tshuaj methyl hloov pauv raws li coenzyme, nws poob ib pawg methyl thiab decomposes rau hauv S-adenosyl pawg Histidine. .
