- HYDROLYSIS OF CARBOHYDRATES INTRODUCTION: Hydrolysis is the process where water is used to break long polysaccharide chains into smaller chains or into simple carbohydrates. Disaccharides can be hydrolyzed into two monosaccharaides units by the use o an enzyme or acid. Sucrose is table sugar which yields glucose and fructose while lactose gives glucose and galactose after hydrolysis. Starch is a homopolysaccharide made up of d-glucose polymer. They are reserved carbohydrates of plants. They are made of two types of polymers namely: amylose (10-30%), no linear and has a 1,4 link and amylopectin (70-90%) is branched having the a 1,4 link and a 1,6 link. Objectives: At the end of the activity, the student can: 1. Hydrolyze the carbohydrate into its monosaccharide unit. 2. Test the products of hydrolysis. Reagents: 6 ml Benedict's reagent, 3 ml Seliwanoff's reagent, 1 ml iodine in KI, 4 ml 3M HCI, 4 ml 3M NaOH, 30 ml distilled water, 0.5 g starch, 0.5 g sucrose Materials: 12(20 ml Test…Describe aldoses and ketoses. Describe triose, tetrose, pentose, hexose and heptose. Describe monosaccharide and list at list three examples. Describe disaccharide and list at list three examples. Describe polysaccharide and list at list three examples. Describe functions of carbohydrates. Describe the polymerization process of carbohydrates. Describe the degradation process of carbohydrates. What is the bond between sugars in a polysaccharide? Describe the function of sugars in protein structures and functions.Refer to the figure below. Determine whether the given descriptions between the relationship of glucose and galactose is correct or incorrect. * сно ÇHO H OH HO-H H- -OH HO-H HO H- H-OH ČH,OH D-Glucose -H -OH H- -он CH,OH D-Galactose CORRECT INCORRECT Glucose and galactose are both Aldohexoses They constitute the structure of the disaccharide maltose They are epimers at carbon 4 They are not mirror images of each other, neither an enantiomeric pair
- Which statement about the glycoprotein shown below is true? OH CH₂OH OH HN HN-C =0 CH3 H₂ Protein CH N-H Protein It contains a deoxyribose sugar that could be metabolized by human enzymes. O The monosaccharide is attached to the protein via nitrogen in a residue's a-amine. It contains a ribose sugar that could not be metabolized by human enzymes. The monosaccharide is attached to the protein via nitrogen in a residue's side chain.Consider the following statements: (1) Complete hydrolysis of a disaccharide produces only monosaccharides. (2) Dihydroxyacetone, galactose, and ribose are all hexoses. (3) Both amylopectin and glycogen are branched glucose polymers. Only one of the statements is true. Two of the three statements are true. All three statements are true. None of the statements are true.* Which of the following statements regarding the reaction of monosaccharide is INCORRECT? Oxidation of sugars using enzymes produces aldaric or dicarboxylic acidic sugar Reduction of the carbonyl group of aldoses and ketoses produces sugar alcohol In acidic solutions, the hydroxyl group of hemiacetals reacts with alcohol to form acetals for glycosides Amino sugars are formed out from the replacement of one of the hydroxyl groups of monosaccharide None of the given options

O Ribose V Galactose V Mannose Amylose O FructoseAmylose is comprised of glucose monomers connected by what kind of glycosidic bond? a (1 -->4) a (1 --> 6) b (1 --> 4) b (1 --> 6) None of the aboveMonosaccharides can be chemically modified by a variety of reactions. Aldoses can be by Tollen's reagent or Benedict's reagent. Monosaccarides can react with carboxylic acids, phosphoric acid, or sulfuric acid to form The hydroxyl group on carbon two can be replaced with a group to form sugars.
