Beschreibung

General description

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).

Application

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

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.

Biochem/physiol Actions

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.

Vitamin D agiert durch einen Rezeptor, der ein Mitglied der ligandenabhängigen Transkriptionsfaktor-Obergruppe ist. Es moduliert das Wachstum und die Differenzierung von normalen Zellen und Krebszellen. Hat wachstums- und Metastasenbildungs-hemmende Effekte auf Brust-, Dickdarm- und Prostatakrebszellen. Aktivierte Vitamin D-Rezeptoren in Darm- und Knochenzellen halten die Calciumabsorption und die Homöostasie aufrecht.

Vitamin D wirkt durch einen Rezeptor, der die Proliferation und Differenzierung von normalen und von Krebszellen moduliert.
