G cells or gastrin cells secrete gastrin. They works in conjunction with gastric chief cells and parietal cells. The peptide hormone bombesin also stimulates gastrin from G cells.
In anatomy, the G cell or gastrin cell, is a type of cell in the stomach and duodenum that secretes gastrin. It works in conjunction with gastric chief cells and parietal cells. G cells are found deep within the pyloric glands of the stomach antrum, and occasionally in the pancreas and duodenum. The vagus nerve innervates the G cells. Gastrin-releasing peptide is released by the post-ganglionic fibers of the vagus nerve onto G cells…

Pepsinogens are mainly grouped in 5 different groups based on their primary structure
1. Pepsinogen A (also called pepsinogen I) 2. Pepsinogen B 3. Progastricsin (also called pepsinogen II and pepsinogen C) 4. Prochymosin (also called prorennin) 5. Pepsinogen F (also called pregnancy-associated glycoprotein).

Gastric lipase
Gastric lipase, also known as LIPF, is an enzymatic protein that, in humans, is encoded by the LIPF gene. Function Gastric lipase is an acidic lipase secreted by the gastric chief cells in the fundic mucosa in the stomach. It has a pH optimum of 3–6. Gastric lipase, together with lingual lipase, comprise the two acidic lipases. These lipases, unlike alkaline lipases (such as pancreatic lipase), do not require bile acid or colipase for…
