| 25-Hydroxy Vitamin D3 3,3-Aminopropyl Ether | Vitamin D3 analog. Calcifediol (INN), also known as calcidiol, 25-hydroxycholecalcifero l, or 25-hydroxyvitamin D (abbreviated 25(OH)D),[1] 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.[2] At a typical daily intake of vitamin D3, its full conversion to calcifediol takes approximately 7 days.[3] 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.[4][5]. Group: Biochemicals.

| 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.
