This is useless. Press the Back button. Thank you. I apologize for wasting your time. Nutrients: Carbohydrates and lipids Key Words: Carbohydrates Monosaccharides, Disaccharides, Polysaccharides alpha and beta linkages, Starch, cellulose, hemicellulose, lignin, soluble fiber, insoluble fiber, pectins, gums Lipids Fats, oils, saturated and unsaturated fatty acids, triglycerides, essential fatty acids Concepts What is the importance of an alpha and beta linkage? What is an essential fatty acid? Describe cellulose, starch, and lignin in terms of a plant. Describe the roles of soluble and insoluble fiber. Determine functions of fats in addition to providing energy Define Carbohydrates (CHO) Most follow the (CH2O)n formula Primarily 6 carbon (above) and 5 carbon sugars Occur as monosaccharides (ex glucose) disaccharides (ex. lactose) and polysaccharides (starch) Fiber: Structural carbohydrates or cell wall components, chains of sugars connected by beta linkages Soluble fibers (pectins, gums, mucilages which make oatmeal or apple sauce gooey) are not structural components per se, but microbes, not pancreatic enzymes, break the linkages CHO digestion Pancreatic enzymes can break the alpha linkage, but not the beta linkages. Exception is lactose, which is a beta linked sugar Monosaccharides cross the intestinal lining, glucose and Na coabsorbed.
