Digestion continued

Continuous EN is preferred for initiation, for critically ill patients, and for patients with limited absorption capacity because of rapid GI transit time or severely impaired digestion. Continuous EN has the advantage of being well tolerated. It has the disadvantages of cost and inconvenience owing to pump and administration sets. 

Protein digestion continues in the small intestine where the enzymes trypsin, chymotrypsin, elastase, and others catalyze the hydrolysis of peptide bonds at different sites in the protein. For instance, chymotrypsin cleaves peptide bonds on the carbonyl side of aromatic amino acids and trypsin cleaves peptide bonds on the carbonyl side of basic amino acids. Together these proteolytic enzymes degrade large dietary proteins into amino acids that can be absorbed by cells of the small intestine. 

The acidic gastric juice enters the duodenum, the upper part of the small intestine, where digestion continues. Secretions from the exocrine pancreas (approximately 1.5 liters/day) flow down the pancreatic duct and also enter the duodenum. These secretions contain bicarbonate (HC03 ), which neutralizes the acidic pH of stomach contents, and digestive enzymes, including pancreatic a-amylase.

The digestion and metabolism of carbohydrates is a complex biochemical process. It starts in the mouth, where the enzyme amylase in the saliva begins the hydrolysis of starch to maltose and temporarily stops in the stomach, where hydrochloric acid deactivates the enzyme. Digestion continues in the intestines, where the hydrochloric acid is neutralized and pancreatic enzymes complete the hydrolysis to maltose. The enzyme maltase then catalyzes the digestion of maltose to glucose ... 

Microbial digestion continues in the large intestine of ruminants volatile fatty acids and microbial protein are produced, but the protein cannot be subsequently digested and absorbed by the host animal.
