Structural Requirements for the Interaction of lcu,25-(OF&Vitamin D, with Its Chick Intestinal Receptor System*


The mechanism by which lac,25-dihydroxycholecalciferol (lcu,25-(OH),D,), the biologically active metabolite of cholecalciferol (vitamin D,), stimulates intestinal calcium absorption has been shown to involve an interaction of the steroid with a specific cytosol-chromatin receptor system in this target organ. Thus, la,25(OH),D, binds to a specific… (More)
