DETAILS

Description (简体中文)

Biochem/physiol Actions
Cholecalciferol is an inactive form of vitamin D3 which undergoes various levels of hydroxylation to form active vitamin D3 analogs. 1α-Hydroxyvitamin D3 (alfacalcidol) is a synthetic analog that is metabolized to 1,25-dihydroxycholecalciferol, the biologically active form of vitamin D3. Other analogues of cholecalciferol result from different hydroxylations. 25-dihydroxycholecalciferol is a the major circulating form of vitamin D3 and a physiological precursor of 1α,25-Dihydroxycholecalciferol. The conversion is catalyzed by 25-Hydroxyvitamin D3 1-α-hydroxylase (VD3 1A hydroxylase) also known ascytochrome p450 27B1 (CYP27B1).
