NUTR 200 Lecture Notes - Lecture 8: Stachyose, Dietary Fiber, Raffinose
Document Summary
Fructose metabolized to glucose in the liver. Starches the glucose storage molecules of plants. Glycogen: long, branched chains of glucose molecules, the glucose storage molecule of animals found in the liver and muscles. Soluble dissolve in water; fruits, vegetables, rice bran, psyllium seed. Funcions delays gastric emptying, slows glucose absorpion, Insoluble do not dissolve in water; whole grains, vegetables. Funcions increases fecal bulk decreases intesinal transit ime. Cellulose : long, unbranched chains of glucose. 4/13/16: linked together in such a way that they cannot be digested by humans, the primary structural molecule of plants. Reduces blood cholesterol (reduces risk of heart disease) Reduce the risk of a variety of chronic diseases. Divericulosis (formaion of bulging pockets in wall of colon) Both carbohydrates and fats supply energy for daily aciviies. Energy red blood cells rely on glucose. Glycolysis - pathway for energy producion from glucose. Amdr (acceptable macronutrient density range) = 45-65% total energy intake.
