HUMNNTR 2210 Lecture Notes - Lecture 7: Corn Syrup, Amylopectin, Amylose
Document Summary
Section 4. 1: carbohydrates our most important energy source. Glycogen, carbohydrate made of multiple glucose molecule: stored in liver and muscle. Photosynthesis: plants changing energy to glucose. Six-carbon, usually exists in a ring form. Class of sugars formed by chemical bonding of two monosaccharides. Lactose (galactose and glucose: milk products. Maltose (glucose and glucose: fermentation, alcohol production. Polysaccharides: starch and glycogen, carbs containing many glucose units, from 10 to 1000 or more. Amylose: digestible straight chain type of starch composed of glucose units. Amylopectin: digestible branded chain type of starch. Dietary fiber: cellulose, hemicelluloses, pectin, gums, mucilage, the non-carbohydrate lignin. Starch: amylose straight chain polymer, amylopectin highly branched polymer. Stored form of carbohydrates for animals and humans. Insoluble or non-fermentable fiber: cellulose, hemicellulose, lignin, not fermented by the bacteria in the colon. Soluble or viscous fiber: gum, pectin, mucilage, fruit, vegetable, rice bran, psyllium seed. Fiber added to food: provides health benefits.
