The role of vitamin d

1, maintain the stability of serum calcium and phosphorus concentration. When serum calcium concentration is low, parathyroid hormone secretion is induced and released to kidney and bone cells. In kidney, pth not only stimulates carboxylase at 1 position and inhibits carboxylase at 24/position, but also promotes phosphorus to be excreted from urine and calcium to be reabsorbed in renal tubules.

2. The carboxylase that promotes the delivery of calcium to the 1 position of the offspring during pregnancy and lactation is affected not only by the concentration of calcium and phosphorus in serum and the supply of calcium and phosphorus in diet, but also by kinetin. After menopause, the concentration of 1, 25-(OH)2-VD3 in women is reduced, and it is easy to have symptoms such as osteomalacia.
