Beschreibung

Derived from cholesterol, vitamin D is biosynthesized from its prohormone cholecalciferol (D3), the product of solar ultraviolet irradiation of 7-dehydrocholesterol in the skin. In 1966, it was first recognized that vitamin D must undergo activation via two oxidative metabolic steps. The first oxidation to 25-hydroxycholecalciferol (25(OH)D3: calcifediol; Calderol) occurs in the endoplasmic reticulum of the liver and is catalyzed by vitamin D 25-hydroxylase. This activation step is not regulated by plasma calcium concentrations. The major circulating form (10–80 μg/mL) is 25(OH)D3, which also is the primary storage form of vitamin D.

Vitamin D4 is the active analogue of Vitamin D.

Biologische Funktion

Sterol-specific cytoplasmic receptor proteins (vitamin D receptor) mediate the biological action of vitamin D. The active hormone is transported from the cytoplasm to the nucleus via the vitamin D receptor, and as a result of the interaction of the hormone with target genes, a variety of proteins are produced that stimulate the transport of calcium in each of the target tissues Active vitamin D works in concert with PTH to enhance active intestinal absorption of calcium, to stimulate bone resorption, and to prohibit renal excretion of calcium. If serum calcium or 1,25-calcitriol concentrations are elevated, then vitamin D 24-hydroxylase (in renal mitochondria) is activated to oxidize 25(OH)D3 to inactive 24,25-dihydroxy-cholecalciferol and to further oxidize active vitamin D to the inactive 1,24,25-trihydroxylated derivative. Both the 1,24,25-trihydroxylated and the 24,25-dihydroxylated products have been found to suppress PT H secretion as well. The biosynthesis of vitamin D is tightly regulated based on the serum concentrations of calcium, phosphate, PTH, and active vitamin D.
