Vitamin D3-d7 is intended for use as an internal standard for the quantification of vitamin D3 (Item No. 11792) by GC- or LC-MS. Vitamin D3 is a biologically inactive precursor to calcitriol (Item No. 71820) that is converted to active metabolites in vivo.{23284,15096} Vitamin D3 is obtained from dietary sources, including fish, or formed in the epidermis via photolytic conversion of 7-dehydro cholesterol (Item No. 14612) to previtamin D3 by UVB radiation, followed by isomerization to vitamin D3.{19039,23286} Vitamin D3 can then be converted to 25-hydroxy vitamin D3 (Item No. 9000683) in the liver by the cytochrome P450 (CYP) isoform CYP2R1 before being converted to calcitriol by CYP27B1 in the kidney.{15096,19039} Formulations containing vitamin D3 have been used in the treatment of osteoporosis.
