Cardiopulmonary rehabilitation. Cardiac rehabilitation (CR) is a branch of rehabilitation medicine/Physical Therapy dealing with optimizing physical function in patients with cardiac disease or recent cardiac surgeries. CR services can be provided during hospitalization for the event or in an outpatient setting.
Pepsin is the active protein-digesting enzyme of the stomach. Pepsin acts on protein molecules by breaking the peptide bonds that hold the molecules together. Digestion of protein is completed in the small intestine by the pancreatic enzymes trypsin, chymotrypsin, and carboxypeptidase. These enzymes also get some help from the brush border enzymes found in the small intestine.
Page 5: Protein digestion begins in the stomach â¢ The enzyme pepsin (activated from pepsinogen by HCl) begins the digestion of proteins in the stomach â¢ Pepsin (optimal pH ~2) breaks the peptide bond between tyrosine and phenylalanine amino acids, thereby producing peptide fragments and a few individual amino acids â¢ The neutral pH of the duodenum denatures pepsin, rendering it inactive Page 6: Most digestion and absorption occur in the small intestine â¢ Most chemical digestion and nearly all the absorption occur in the small intestine â¢ Pancreatic digestive enzymes alone are sufficient to digest carbohydrates and proteins â¢ Pancreatic lipase is essential for the bulk of fat digestion
