Ascorbic Acid nrog CAS 50-81-7
Vitamin C, tseem hu ua L-ascorbic acid, yog cov khoom noj khoom haus tseem ceeb rau cov tsiaj txhu thiab ob peb lwm yam tsiaj txhu.
Ascorbic acid yog metabolically tsim nyob rau hauv feem ntau cov kab mob, tab sis tib neeg yog qhov tshwj xeeb tshaj plaws.
Qhov paub zoo tshaj plaws yog qhov tsis muaj vitamin C tuaj yeem ua rau scurvy. Lub pharmacophore ntawm vitamin C yog cov ascorbic acid ion. Hauv cov kab mob muaj sia, vitamin C yog cov tshuaj antioxidant vim nws tiv thaiv lub cev ntawm kev hem thawj ntawm oxidants, thiab vitamin C kuj yog ib qho coenzyme.
