Holy Name University Structural Polysaccharides Glycolipids and Glycoproteins Questions

I’m working on a biochemistry exercise and need guidance to help me learn.

1. 18.110 Which of the disaccharides maltose, cellobiose, lactose, and sucrose has each of the following characteristics? More than one disaccharide may have the indicated characteristic.
   a. Two different monosaccharide units are present.
   b. A beta (1 : 4) glycosidic linkage is present.
   c. One of the monosaccharide components is fructose.
   d. Hydrolysis produces a single substance.
2. 18.112 Indicate whether or not each of the following disaccharides give a positive Benedict’s test.
   a. Maltose b. Cellobiose c. Sucrose d. Lactose
3. 18.116 For each of the structures in Problem 18.114, specify whether the disaccharide is in a configuration or a b configuration, or neither.
4. 18.126 Indicate which of the terms monosaccharide, disaccharide, reducing sugar, anomers, enantiomers, and aldohexose applies to both members of each of the following pairs of substances. More than one term may apply to a given pair of substances.
   a. a-D-Glucose and a-D-galactose
   b. Sucrose and cellobiose
   c. Glyceraldehyde and dihydroxyacetone
   d. D-Ribose and L-ribose
5. 18.150 Indicate whether or not each of the following is a correct characterization for chitin.
   1. It is an unbranched polymer.
   2. Two different types of monomers are present.
   3. Glycosidic linkages present are the same as those in cellulose.
   4. The monomers present are glucose derivatives rather than glucose itself

6. 1. Indicate whether or not each of the following characterizations applies to (1) both cellulose and chitin (2) to cellulose only (3) to chitin only or (4) to neither cellulose nor chitin.
      a. Structural polysaccharide
