It is an active metabolite of cholecalciferol, which performs important functions in regulation of the calcium balance and the bone metabolism. It has a role as a bone density conservation agent. It is a member of D3 vitamins, a seco-cholestane, a hydroxycalciol and a diol. It is functionally related to a calciol."}]
