The distinction between neuropeptide and peptide hormone has to do with the cell types that release and respond to the molecule; neuropeptides are secreted from neuronal cells (primarily neurons but also glia for some peptides) and signal to neighboring cells (primarily neurons).oth neuropeptides and peptide hormones are synthesized by the same sets of enzymes, which include prohormone convertases and carboxypeptidases that selectively cleave the peptide precursor at specific processing sites to generate the bioactive peptides.
PTH stands for parathyroid hormone. It is a protein hormone released by the parathyroid gland. The parathyroid glands are located in the neck, near or attached to the back side of the thyroid gland.Parathyroid hormone controls calcium, phosphorus, and vitamin D levels in the blood and bone.Release of PTH is controlled by the level of calcium in the blood. Low blood calcium levels cause increased PTH to be released, while high blood calcium levels block PTH release.A laboratory test can be done to measure the amount of PTH in your blood.TH stands for parathyroid hormone. It is a protein hormone released by the parathyroid gland. The parathyroid glands are located in the neck, near or attached to the back side of the thyroid gland.
