Biochem/physiol Actions
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. 23,25-Dihydroxyvitamin D3 is synthesized by the human placenta and by kidney cortex mitochondria.

To elucidate the biosynthesis of 25-hydroxyvitamin D3-26,23-lactone, various vitamin D3 derivatives were incubated individually with kidney homogenates prepared from vitamin D3-supplemented chicks, a preparation known to produce the 25-hydroxyvitamin D3-26,23-lactone from 25-hydroxyvitamin D3. The 25-hydroxyvitamin D3-26, 23-lactone produced in vitro

We measured 24,25-dihydroxyvitamin D [24,25(OH)2D] levels in patients treated with chronic ambulatory peritoneal dialysis (CAPD), before and after receiving vitamin D2 or 1 alpha-hydroxyvitamin D3 (1 alpha-OH-D3). Vitamin D2 administration led to an increase in 25-hydroxyvitamin D (25-OH-D) and a

A new metabolite of 23,25-dihydroxyvitamin D3 has been generated with kidney homogenates prepared from vitamin D treated chicks. The metabolite was purified with three high-performance liquid chromatographic steps and was identified as 23-keto-25-hydroxyvitamin D3 by ultraviolet absorption spectroscopy, mass spectrometry
