A person has not eaten fats for a long time, but received a sufficient amount of carbohydrates and proteins. After that, he was diagnosed with symptoms of a lack of vitamins, especially vitamins A, D, E, and K. Suggest the possible reason of hypovitaminosis. Water-soluble vitamins couldn't be absorbed. Fats take part in catabolism of vitamins. The diet, rich in proteins and carbohydrates, didn't contain vitamins. Micelles couldn't be formed to transport vitamins. O Fat-soluble vitamins couldn't be absorbed.
(a) What is the charge of bile acids in the small intestine, where the pH is 7–8? (b) According to one hypothesis, bile acids are toxic to bacteria and so could help limit their growth in the intestine. Propose a mechanism for this bactericidal activity.
Would substituting fiber and complex carbohydrates (larger % cellulose) for the simple sugars and starches (high sucrose and amylose/amylopectin) help Morgan lose weight, why? Yes, because complex carbohydrates like cellulose are largely indigestible so they pass through the digestive tract without being absorbed. Yes, cellulose contains less glucose residues than amylose or amylopectin. Yes, because the fructose in sucrose is much more responsible for weight gain than the glucose. No, because cellulose, amylose, and amylopectin are all composed of glucose so it doesn’t matter.
