SULTKONTROL FØDEINDTAGELSE[redigér | rediger kildetekst]

Leptin is a hormone secreted from fat cells that helps to regulate body weight. The name leptin is derived from the Greek word 'leptos' meaning thin. It is sometimes referred to as the 'Fat Controller'.

Ghrelin is produced by the stomach. Among its numerous functions, ghrelin increases appetite and stimulates the release of growth hormone.

Peptide YY is a hormone made in the small intestine. It helps to reduce appetite and limit food intake.

https://www.futurity.org/overeating-brain-cells-1874922/ POMP og AgRP The gene called POMC (short for pro-opiomelanocortin) has multiple functions: it encodes a stress hormone called ACTH, a natural opioid called beta-endoprhin, and several other molecules called melanocortins. POMC’s products get opposition from products of the AgRP gene, whose name is short for Agouti-Gene-Related Peptide. In general, POMC acts like a brake on feeding when it gets certain signals from the body, and AgRP acts like an accelerator pedal.

Peptide

gastrin-34 ("big gastrin") 34 aminosyrer

Gastrin is a peptide hormone that stimulates secretion of gastric acid (HCl) by the parietal cells of the stomach and aids in gastric motility. It is released by G cells in the pyloric antrum of the stomach, duodenum, and the pancreas.

Gastrin binds to cholecystokinin B receptors to stimulate the release of histamines in enterochromaffin-like cells, and it induces the insertion of K+/H+ ATPase pumps into the apical membrane of parietal cells (which in turn increases H+ release into the stomach cavity). Its release is stimulated by peptides in the lumen of the stomach.
