Part Descriptions

LP40352-4   25-Hydroxycalciferol
Naturally occuring Vitamin D (diet, dermal synthesis) is biologically inactive and requires enzymatic conversion to active metabolites. In the liver, Vitamin D is converted to 25-hydroxyvitamin D, the major circulating form of vitamin D, and then to 1,25-dihydroxyvitamin D, the active form of vitamin D. 1,25-dihydroxyvitamin D in turn binds to the intracellular vitamin D receptor.
