Preparation and Storage

Background: Vitamin D3

25-hydroxy-vitamin D₃ (25(OH)D₃) is synthesized in the liver and is the primary circulating form of vitamin D.  Its blood concentration, which reflects 25(OH)D₃ produced by exposure to ultraviolet B, as well as dietary and vitamin D supplementation, is felt to be the best indicator of vitamin D status.  25(OH)D₃ is metabolized to 1 alpha,25(OH)₂D₃ in the  proximal tubular cells of the kidney by the enzyme 1 alpha -hydroxylase.   The vitamin D structure is similar to that of classic steroid hormones, such as estradiol, cortisol, and aldosterone in that they have the same root cyclopentanoperhydrophenanthrene ring structure.  It has been shown that the active steroid hormone 1 alpha,25(OH)₂D₃ is essential for life in higher animals.  Besides playing important roles in calcium homeostasis and bone mineral metabolism, it is now known to play a role in cellular differentiation, inhibition of cell growth, immune regulation and the prevention of neoplastic transformation. The active form of vitamin D₃, 1 alpha,25(OH)₂D₃, acts both through its cellular receptor, the vitamin D receptor (VDR), and through other extrarenal targets in an autocrine and paracrine manner where 1 alpha -hydroxylase is present.
