Pepsinogen is the precursor molecule of the very potent protein-digesting enzyme pepsin. Hydrochloric acid is normal dilute HCl. The mucosa contains specialized cells and glands that produce hydrochloric acid and digestive enzymes to help digest food. The protein digesting enzyme pepsin is activated by exposure to hydrochloric acid inside the stomach. enzymes break down lipids (fats and oils) into fatty acids and glycerol; Carbohydrates. Lastly, the parietal cell secretes hydrochloric acid, which it is responsible for the stomach’s acidic environment [11]. Pepsin breaks down the protein in the food into smaller particles, such as peptide fragments and amino acids. Despite being hydrophobic, the small size of short-chain fatty acids enables them to be absorbed by enterocytes via simple diffusion, and then take the same path as monosaccharides and amino acids into the blood capillary of a villus. Short-chain fatty acids are relatively water soluble and can enter the absorptive cells (enterocytes) directly. There are many enzymes secreted in the stomach , but the most portant are 1) hydrochloric acid and 2) the gastric juice. The chief cell secretes an enzyme known as Pepsinogen, which is an inactive form of pepsin that helps to denature proteins from absorbed nutrients inside the stomach. Parietal cells (also called oxyntic cells) are the stomach epithelium cells which secrete gastric acid. They are chains of amino acids that join together to perform a specific function. Which enzymes are responsible for the final chemical breakdown of carbohydrates, amino acids, and nucleic acids? Enzymes are made of proteins. A vast number of gastric pits dot the surface of the epithelium, giving it the appearance of a well-used pincushion, and mark the entry to each gastric gland, which secretes a complex digestive fluid referred to as gastric juice. the carboxypeptidase, which remove amino acids from C-terminal end, and are produced by the exocrine pancreas; the aminopeptidase, which act on the N-terminal end, and are produced by the enterocytes. The stomach releases enzymes to digest carbohydrates. Absorbed lipids are transported from intestinal epithelial cells to the lymphatic system in what form? The mucosa in the cardiac and pyloric regions of the stomach release mucus that helps protect the lining of the stomach from the acid produced for digestion. Pepsinogen is then activated by the stomach acid into its active form, pepsin. Pepsin is the main gastric enzyme: It is produced by the stomach cells called "chief cells" in its inactive form pepsinogen, which is a zymogen. Enzymes are responsible for the chemical reactions that occur in a cell. Activation of Chymotrypsinogen. 48. The stomach mucosa’s epithelial lining consists only of surface mucus cells, which secrete a protective coat of alkaline mucus. These enzymes are synthesized and secreted in an inactive form, called zymogens or proenzymes. - Chief cells, also found within the gastric pits of the stomach, produce two digestive enzymes: pepsinogen and gastric lipase.
