Działania biochem./fizjol.

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).

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

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

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

Vitamin D and Prevention of Human Disease

Vitamin D2 (ergocalciferol) is naturally synthesized from ergosterol by invertebrates, fungi, and plants in response to ultraviolet B irradiation, while vitamin D3 synthesis (cholecalciferol) is uniquely initiated in the skin of vertebrates. During sun exposure, ultraviolet B photons are absorbed by 7-dehydrocholesterol, which is found within the plasma membranes of epidermal and dermal skin layers. This reaction yields an unstable derivative of 7-dehydrocholesterol, named precholecalcitrol, which rapidly rearranges to vitamin D3. Vitamin D binding protein (DBP) is a carrier protein responsible for drawing vitamin D3 from the plasma membrane into the dermal capillaries within the extracellular space.

Analysis of Vitamin D in Milk and Infant Formula using UHPLC/MS/MS per AOAC Method 2011.11

While quantitative analysis was performed for Vitamins D2 and D3, the samples were scanned for the presence of the 25-hydroxy metabolites.
