胆钙化醇是维生素D3的一种失活形式，它在经历各种水平的羟基化后可形成活性的维生素D3类似物。 1α-羟基维生素D3（α-骨化醇）是一种合成类似物，其可代谢为1,25-二羟胆钙化醇（维生素D3的生物活性形式）。胆钙化醇的其他类似物可由不同的羟基化产生。 25-二羟胆钙化醇是维生素D3的主要循环形式，是1α，25-二羟胆钙化醇的生理前体。该转化由25-羟基维生素D3 1-α-羟化酶（VD3 1A羟化酶）——也称为细胞色素p450 27B1 (CYP27B1)——进行催化。

Cholecalciferol must be regarded as a pro-hormone rather than a vitamin, since it is normally produced in skin under the influence of ultraviolet light. Cholecalciferol must be metabolized in liver to 25-hydroxycholecalciferol and subsequently to 1,25-dihydroxycholecalciferol before it can act

The major circulating form of vitamin D is 25-hydroxycholecalciferol [25(OH)D3], which is delivered to target tissues in complex with the serum vitamin D binding protein (DBP). We recently observed that mammary cells can metabolize 25(OH)D3 to 1,25-dihydroxycholecalciferol [1,25(OH)(2)D3], the vitamin

1alpha,25-dihydroxycholecalciferol [1alpha,25(OH)2D3], the active form of cholecalciferol, is a negative growth regulator of breast cancer cells. CYP27B1 is a cytochrome P450-containing hydroxylase expressed in kidney and other tissues that generates 1alpha,25(OH)2D3 from an inactive vitamin D precursor 25-hydroxycholecalciferol [25(OH)D3]. In

Suboptimal vitamin D status was recently acknowledged as an independent predictor of cardiovascular diseases and all-cause mortality in several clinical settings, and its serum levels are commonly reduced in Rheumatoid Arthritis (RA). Patients affected by RA present accelerated atherosclerosis and

Vitamin D has immunomodulatory effects that might aid clearance of mycobacterial infection. We aimed to assess whether vitamin D supplementation would reduce time to sputum culture conversion in patients with active tuberculosis. We did this randomised, double-blind, placebo-controlled, superiority trial
