Hydrogen, Oxygen, Carbon 1 of 19 General Formula of a Carbohydrate? Cm(H2O)n 2 of 19 Monosaccharide examples Glucose, fructose, ribose 3 of 19 Disaccharide examples lactose, sucrose 4 of 19 Polysaccharide examples glycogen, cellulose, starch 5 of 19 How many carbons does glucose have? 6 (hexose) 6 of 19 What is the difference between alpha and beta glucose? Alpha - Hydrogen is above on both C1 and C4 Beta - Hydrogen is below on C1 (above on C4) 7 of 19 Hydrogen bonds between hydroxyl groups and water molecules mean that glucose is what? Polar and soluble in water 8 of 19 Glucose + glucose = ? Maltose 9 of 19 Glucose + fructose = ? Sucrose 10 of 19 Glucose + galactose = ? Lactose 11 of 19 Starch - alpha or beta glucose? Alpha glucose 12 of 19 Glycogen - alpha or beta glucose? Alpha glucose 13 of 19 Cellulose - alpha or beta glucose? Beta glucose 14 of 19 Main energy storage in animals? Glycogen 15 of 19 Glycogen - highly branched means what? Glucose and therefore energy can be released quickly for respiration 16 of 19 Main energy store in plants? Starch 17 of 19 Types of starch? Amylose (unbranched chain, coiled, 1,4 glycosidic bonds) Amylopectin (branched, 1,4 and 1,6 glycosidic bonds) 18 of 19 Cellulose structure? Microfibrils are strong threads which are made of long cellulose chains joined together by hydrogen bonds and they provide structural support in plants cells 19 of 19
