9,10-Secocholesta-5,7,10(19)-trien-3beta-ol is a secosteroid compound, which is predominantly derived from the photochemical conversion of 7-dehydrocholesterol in the skin upon exposure to ultraviolet B radiation. This compound undergoes a series of hepatic and renal hydroxylations to form active vitamin D metabolites, such as calcitriol. These active forms modulate calcium and phosphate homeostasis through a nuclear receptor-mediated mechanism that governs gene expression relevant to mineral metabolism.
