Vitamin D must be metabolized to 25-OH-D3 or calcidiol in the liver and subsequently to 1,25-(OH)2D3 (calcitriol) in the kidney to produce its physiological actions. Calcitriol stimulates calcium and phosphorus transport reactions in the small intestine and together with parathyroid hormone stimulates calcium transport reactions in bone and kidney. In the small intestine calcitriol brings about its response in a complex manner. It provides a very rapid response on existing villus cells, causing… CONTINUE READING
