Common Name25,26-Dihydroxyvitamin D3
Description25,26-(OH)2D3 is a renal microsomal 25-OH-D3 metabolite, whose plasma concentration increases during vitamin D excess concomitantly with an increase in the concentration of lactone. This observation considered with the related structural features of 25,26-(OH)2D3 and lactone (both are oxidized at (C-26) suggested that 25,26(OH)2D3, a metabolite of unknown function, could be a precursor to lactone. In fact, it has been reported that functionalization of C-26 and subsequent lactone formation occurs exclusively in kidney. However, rigorous examination has unambiguously excluded 25S,26-(OH)2D3, the naturally occurring form as a significant lactone precursor. (PMID: 6286629 ) [HMDB]
