In addition to being produced in the pancreas, lipase is also produced in the stomach. Do you believe the structure of pancreatic lipase the same as gastric lipase? Explain your answer. 10. Antacids work by neutralizing acids, bringing the pH of the stomach to a range of pH = 6 to 7. What is the effect of taking an antacid on a person's ability to digest proteins? Explain your answer.Y ANTIBODIES DIETARY B12 PERNICIOUS ANAEMIA HYDROXYCOBALAMIN 5. Pernicious anemia is a disease in which the intestine is unable to absorb vitamin B12, frequently due to the loss of the generically named "intrinsic factor" produced by the parietal cells of the stomach lining. Intrinsic factor is a glycoprotein that binds to vitamin B₁2 and is required for its uptake in the ilium. Vitamin B12 is synthesized only by microbes, and we get it either from digesting animal protein or from our commensal microbiome. Vitamin B₁ is unique among metabolic cofactors in that it contains the trace element cobalt, coordinated in a corrin ring structure that is similar to the porphyrin ring system in heme. Loss of intrinsic factor, often through autoimmunity, results in the inability to absorb B12 and ultimately a loss of red blood cells that results in anemia and can be deadly ("pernicious"). ILEUM NUMBNESS (a) In pernicious anemia, N 5-methyltetrahydrofolate accumulates, and cells run out of…Work 2. The role of bile in digestion. Hepatic circulation of bile acids. Bile contains salts of bile acids, in particular, glycocholic and taurocholic. They reduce the surface tension of water and thereby contribute to the emulsification of fats, which facilitates the enzymatic cleavage of lipids. Further, in the of digestion, bile acids form micelles with lipids and their cleavage products, due to process Img. 19. Micelle structure which fats can be absorbed.
