[Intestinal calcium absorption and vitamin D].
Vitamin D is required for efficient absorption of dietary Ca. Accumulated observations indicated that active form of vitamin D is involved in the three steps of intestinal Ca absorption:incorporation of Ca by epithelial cells through brush border membrane, intracellular Ca movement, and excretion of Ca into systemic circulation via basolateral membrane. It is also known that activated vitamin D takes part in growth and differentiation of intestinal epithelial cells.
