CAS:Luteinizing hormone-releasing hormone (LH-RH), also known as Gonadotropin-Releasing Hormone (GnRH), stimulates the pituitary gland’s production and secretion of luteinizing hormone and follicle-stimulating hormone. LHRH is a decapeptide and is itself secreted by the hypothalamus. It is crucial for human reproduction and is heavily involved in the regulation of ovulation, sexual development and the onset of puberty. When secreted, GNRH binds to the G-protein coupled receptor, gonadotropin-releasing hormone receptor (GNRHR) located on pituitary gonadotrophic cells in the anterior pituitary. Medically, the understanding of GnRH is paramount, due to its involvement in the pathogensis of central hypogonadism. Any obstructions to its function in the reproductive system can result in the development of human pathologically conditions. It is important to note that analogs of GnRH can be used in pharmacology, in the treatment of gynaecological diseases, through blocking the secretion of estrogen secretion from the ovary.

CAS:Calcitonin is a hormone produced by the C cells (also known as parafollicular cells) in the thyroid gland. Its main function is to regulate the levels of calcium and phosphate in the blood. Calcitonin works by inhibiting the activity of osteoclasts, which are cells that break down bone tissue and release calcium and phosphate into the bloodstream. This leads to a decrease in the amount of calcium and phosphate in the blood. Calcitonin is released in response to high levels of calcium in the blood, and it acts to reduce these levels by increasing the excretion of calcium by the kidneys and inhibiting the absorption of calcium by the intestines. It also promotes the storage of calcium in the bones, which helps to maintain their strength and density. Calcitonin may be used therapeutically to treat conditions such as osteoporosis and hypercalcemia (high levels of calcium in the blood) or even diagnostically as a marker for tumors in medullary thyroid cancer.
