11:16 Summary of digestion and absorption of proteins
Digestion and absorption of proteins. Digestion of proteins involves the gradual breakdown of the polypeptide by enzymatic hydrolysis. The entry of a protein into the stomach stimulates the gastric mucosal cells to secrete a hormone called gastrin which in turn stimulates the secretion of 𝐇𝐂𝐥 𝐛𝐲 𝐭𝐡𝐞 𝐩𝐚𝐫𝐢𝐞𝐭𝐚𝐥 𝐜𝐞𝐥𝐥𝐬 𝐨𝐟 𝐭𝐡𝐞 𝐠𝐚𝐬𝐭𝐫𝐢𝐜 𝐠𝐥𝐚𝐧𝐝𝐬 and 𝐩𝐞𝐩𝐬𝐢𝐧𝐨𝐠𝐞𝐧 𝐛𝐲 𝐭𝐡𝐞 𝐜𝐡𝐢𝐞𝐟 𝐜𝐞𝐥𝐥𝐬. In the stomach, pepsin begins the digestion of proteins by hydrolyzing them to smaller polypeptides. The product of the digestion from the stomach passes into the small intestine and it is called chyme which is acidic in nature. Acidic chyme stimulates duodenal mucosal cells to release 2 local hormones called 𝐬𝐞𝐜𝐫𝐞𝐭𝐢𝐧 𝐚𝐧𝐝 𝐜𝐡𝐨𝐥𝐞𝐜𝐲𝐬𝐭𝐨𝐤𝐢𝐧𝐢𝐧. Secretin stimulates the pancreas to secrete bicarbonate, which in the small intestine neutralizes the gastric HCl and abruptly changes the pH to 7. Cholecystokinin stimulates The pancreatic to release proteases: 𝐭𝐫𝐲𝐩𝐬𝐢𝐧, 𝐜𝐡𝐲𝐦𝐨𝐭𝐫𝐲𝐩𝐬𝐢𝐧, 𝐞𝐥𝐚𝐬𝐭𝐚𝐬𝐞,and the 𝐜𝐚𝐫𝐛𝐨𝐱𝐲𝐩𝐞𝐩𝐭𝐢𝐝𝐚𝐬𝐞𝐬 which cleave the polypeptides into oligopeptides and amino acids. Further cleavage of the oligopeptides to amino acids is by enzymes produced from the intestinal mucosal cells. Finally, the amino acids produced by protein digestion are absorbed through the specific transporters of intestinal epithelial cells and enter the blood.
