      • Anatomical structure: liver

        • Prehormon wich is produced by hydroxylation of vitamin D3 (cholecalciferol) in the liver.
        • Calcidiol is then converted in the kidneys (by the enzyme 25(OH)D-1╬▒-hydroxylase) into calcitriol (1,25-(OH)2D3), a secosteroid hormone that is the active form of vitamin D. It can also be converted into 24-hydroxycalcidiol in the kidneys via 24-hydroxylation.
