In this lecture ´´Protein Digestion and Absorption´´ is explained. Section one is about ´´Digestion´´. Initially, educator tells about source of proteins. After that enzyme inhibitors in food sources are discussed. Then digestion in mouth is explained.
Digestion in Stomach
Section two is about ‘’Digestion in Stomach’’. Educator's first theme of discussion is gastric juice. Then pepsin is explained. Alongside activation of pepsinogen is elaborated. Thesis followed by action on milk. Furthermore, action of rennin is pursued. Subsequently, gastriscin is elucidated. Lastly, gelatinase comes under consideration.
Digestion in Duodenum
Section three is about ‘’Digestion in Duodenum’’. Educator primarily focus digestion in duodenum. After that trypsin is discussed. This is followed by activation of trypsin. Then proteolytic functions of trypsin are highlighted. Furthermore, trypsin inhibitors are reported. Subsequently, chymotrypsin is elucidated. Alongside action on milk is pursued. Afterwards, carboxy peptidases are focused. Following this, carboxy peptidases A and carboxy peptidases B are discussed respectively. In the end, educator explains elastase and collagenase elastase.
Digestion in Small Intestine
Section four is about ‘’Digestion in Small Intestine’’. This section is started by the explanation of digestion in small intestine. After that discussion continues on an enzyme enterokinase. Following this, enterokinase action is presented. Then amino peptidases are elucidated. Moreover, prolidase is pursued. Likewise, tri and di-peptidases are elaborated lastly.
Absorption of Amino Acids
Section five is about ‘’Absorption of Amino Acids’’. Educator tells about the site of absorption. After that absorption of peptides and amino acids is exhibited. Then peptides and amino acids in liver are presented. Moreover, rate of absorption is highlighted. Following this, mechanism of absorption is discussed. Moving onward, model for study is presented. Likewise, evidences for “active” absorption is given. Afterwards, role of glutathione in amino acid absorption is explained. Finally, sensitivity to dietary proteins (immunologic response) is pursued.
