Parathyroid hormone (1-34) (human), (C181H291N55O51S2), a peptide with the sequence H2N-SVSEIQLMHNLGKHLNSMERVEWLRKKLQDVHNF-OH, MW= 4117.72. Parathyroid hormone (PTH), parathormone or parathyrin, is secreted by the chief cells of the parathyroid glands as a polypeptide containing 84 amino acids. It acts to increase the concentration of calcium (Ca2+) in the blood, whereas calcitonin (a hormone produced by the parafollicular cells (C cells) of the thyroid gland) acts to decrease calcium concentration. PTH acts to increase the concentration of calcium in the blood by acting upon the parathyroid hormone 1 receptor and the parathyroid hormone 2 receptor(1). Parathyroid hormone regulates serum calcium, It enhances the release of calcium from the large reservoir contained in the bones(2). It enhances active reabsorption of calcium and magnesium from distal tubules and the thick ascending limb(3). It enhances the absorption of calcium in the intestine by increasing the production of activated vitamin D.
