说明

一般說明

Cholecalciferol, also called vitamin D₃, promotes the absorption of calcium and phosphorus in the body to regulate bone growth. It is most commonly found in humans and animals and is produced in our skin when exposed to sunlight. It is used to treat and prevent bone disorders (such as rickets, osteomalacia).

應用

Cholecalciferol has been used as an internal standard in high-performance liquid chromatography (HPLC) to analyze serum vitamin D levels. It has also been used as a standard in liquid chromatography-electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS) to quantify vitamin D3 in sunflower oil.

Cholecalciferol may be used as an analytical reference standard for the determination of the analyte in pharmaceutical formulations by liquid chromatography.

生化／生理作用

维生素 D 借以发挥作用的受体是配体依赖性转录因子超家族的成员。调控正常细胞和癌细胞的增殖和分化。对乳腺癌、结肠癌和前列腺癌细胞具有抗增殖和抗转移作用。肠和骨骼中的活化维生素 D 受体维持着钙的吸收和平衡。

Cholecalciferol is sourced either through the diet or exposing skin to ultraviolet rays. Oral administration of vitamin D3 is readily absorbed and is stored in adipose tissue. Deficiency of vitamin D is often observed in chronic kidney disease.
