| 25-Hydroxy Vitamin D3 3-Sulfate Sodium Salt | 25-Hydroxyvitamin D3 3-Sulfate is a metabolite of 24,25-Dihydroxyvitamin D3 and 25-Hydroxyvitamin D3. Calcifediol (INN), also known as calcidiol, 25-hydroxycholecalcifero l, or 25-hydroxyvitamin D (abbreviated 25(OH)D),is a prehormone that is produced in the liver by hydroxylation of vitamin D3(cholecalciferol) by the enzyme cholecalciferol 25-hydroxylase which was isolated by Michael F. Holick. Physicians worldwide measure this metabolite to determine a patient's vitamin D status.At a typical daily intake of vitamin D3, its full conversion to calcifediol takes approximately 7 days. Calcifediol is then converted in the kidneys (by the enzyme 25(OH)D-1α-hydroxylase) into calcitriol (1,25-(OH)2D3), a secosteroid hormone that is the active form of vitamin D. It can also be converted into 24-hydroxycalcidiol in the kidneys via 24-hydroxylation. Group: Biochemicals.

| Vitamin D3 | Cholecalciferol is a naturally occurring form of vitamin D which is obtained from dietary sources, such as fish, or through the conversion of 7-dehydrocholesterol by ultraviolet light. It is subsequently metabolized to 25-hydroxyvitamin D3 and the active form 1,25-dihydroxyvitamin D3 by cytochrome P450 isoforms in the liver. It could prevent proliferation of cancer cells.

| vitamin D3 24-hydroxylase | This mitochondrial cytochrome P-450 enzyme requires adrenodoxin. The enzyme can perform up to 6 rounds of hydroxylation of the substrate calcitriol leading to calcitroic acid. The human enzyme also shows 23-hydroxylating activity leading to 1,25 dihydroxyvitamin D3-26,23-lactone as end product while the mouse and rat enzymes do not. The initial source of the electrons is NADPH, which transfers the electrons to the adrenodoxin via EC 1.18.1.6, adrenodoxin-NADP+ reductase. Group: Enzymes. Synonyms: CYP24A1. Enzyme Commission Number: EC 1.14.15.16. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-0941; vitamin D3 24-hydroxylase; EC 1.14.15.16; CYP24A1. Cat No: EXWM-0941. |  |
