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