157938-23-3 Usage
General Description
PTH (1-31) (HUMAN) is a synthetic peptide representing the N-terminal 31 amino acids of human parathyroid hormone (PTH). It is a potent regulator of calcium and phosphate homeostasis in the body, primarily by stimulating the release of calcium from bone and increasing the reabsorption of calcium in the kidneys, while also decreasing phosphate reabsorption in the kidneys. PTH (1-31) also plays a role in the regulation of vitamin D metabolism and has been studied for its potential therapeutic applications in conditions such as osteoporosis, chronic kidney disease, and hypoparathyroidism.
