DefinitionThis section has been translated automatically.

Single-chain peptide hormone consisting of 84 amino acids. The synthesis takes place via higher molecular precursors (preproPTH →proPTH→intaktes PTH ) in the epithelial corpuscles. The secretion of the hormone is primarily regulated by the concentration of ionized calcium . Hypercalcemia and 1,25(OH)2-Vit.D3 inhibit PTH secretion. The half-life of PTH in blood is about 2 min.
