23,25-Dihydroxy-24-oxovitamin D₃（Cat No.:I045055）is a bioactive vitamin D₃ metabolite involved in the catabolic pathway of vitamin D regulation. It features hydroxyl groups at the 23 and 25 positions and a keto group at the 24 position, forming part of the inactivation process of calcitriol. This metabolite plays a role in maintaining calcium and phosphate homeostasis by modulating the activity of vitamin D receptors (VDR). It is valuable in studying vitamin D metabolism, endocrine regulation, and bone health. For use in biochemical and physiological research only; not intended for clinical or therapeutic applications.
