How do hormones leptin and grhelin function in the body to regulate appetite?
Weegy: These three hormones, orexin, gherlin and leptin, act on your brain to normalize your drive for food. In this way your body responds appropriately with hunger for breakfast. [ Breakfast is the combination of two words, “break” and “fast”. While ghrelin is an appetite-stimulating peptide, leptin is an appetite-suppressing one. Ghrelin, secreted from the stomach, particularly influences the metabolism of fat tissue by promoting its storage during hard times. Leptin and ghrelin function interdependently in healthy humans. The world leptin means “full” in Greek. Leptin is produced in the fat cells and released in the brain. Leptin gives us a feeling of satisfaction. While ghrelin enhances appetite, leptin acts as a satiety signal to diminish it. Yet, it’s not that simple. There are multiple receptors in fat cells. These produce other hormones, which can interfere in our response to food intake. A balance exists between your fat cells and your appetite. The discovery of ghrelin at the end of the last century, definitely contributed to the understanding of the regulation of appetite and eating behavior. Ghrelin, consisting of 28 amino acids, was first identified in the stomach in 1999. It is produced in glandular cells of the stomach lining, but is also found in the pituitary, the hypothalamus and the pancreas. According to ongoing research, ghrelin has multiple biological roles: for example, ghrelin stimulates the release of growth hormone and also induces a rise in the concentration of other hormones including cortisol. Through these multiple mechanisms ghrelin can accelerate food intake boosting weight. ] (More)
