  • Human placental lactogen (hPL)

    Human placental lactogen (hPL), also called human chorionic somatomammotropin (HCS), is a polypeptideplacental hormone, the human form of placental lactogen (chorionic somatomammotropin). Its structure and function are similar to those of human growth hormone. It modifies the metabolic state of the mother during pregnancy to facilitate the energy supply of the fetus. hPL has anti-insulin properties. hPL is a hormone secreted by the syncytiotrophoblast during pregnancy. Like human growth hormone, hPL…

  • Human chorionic gonadotropin (hCG)

    Human chorionic gonadotropin (hCG) is a hormone for the maternal recognition of pregnancy produced by trophoblast cells that are surrounding a growing embryo (syncytiotrophoblast initially), which eventually forms the placenta after implantation.

  • Prostaglandins (PG)

    The prostaglandins (PG) are a group of physiologically active lipid compounds called eicosanoids  “Eicosanoid Synthesis and Metabolism: Prostaglandins, Thromboxanes, Leukotrienes, Lipoxins”. themedicalbiochemistrypage.org. Retrieved 2018-09-21.  having diverse hormone-like effects in animals. Prostaglandins have been found in almost every tissue in humans and other animals. They are derived enzymatically from the fatty acid arachidonic acid. Ricciotti E, FitzGerald GA (May 2011). “Prostaglandins and inflammation”. Arteriosclerosis, Thrombosis, and Vascular Biology. 31 (5): 986–1000. doi:10.1161/ATVBAHA.110.207449. PMC 3081099. PMID 21508345. Every prostaglandin contains 20 carbon atoms, including…
