Chapter 19, Problem 37P

(a)

Interpretation Introduction

Interpretation: The name of two monosaccharide units present in the following disaccharide should be determined:

Introduction To General, Organic, And Biochemistry, Chapter 19, Problem 37P

Concept Introduction: A sugar formed by joining two monosaccharides is said to be disaccharide.

(b)

Interpretation Introduction

Interpretation: The glycosidic bond should be mentioned in the disaccharide.

Concept Introduction: A covalent bond that joins a group with a carbohydrate (sugar) is said to be a glycosidic bond or linkage.

(c)

Interpretation Introduction

Interpretation: Whether the disaccharide is a reducing or non-reducing sugar should be determined.

Concept Introduction: On oxidation, the aldehyde group is converted to carboxylic acid group resulting in the formation of aldonic acids. Carbohydrates on reacting with mild oxidizing agent to form acid is said to be reducing sugar.

(d)

Interpretation Introduction

Interpretation: Whether the disaccharide will undergo mutarotaion or not should be determined.

Concept Introduction: A change in the specific rotation of an optically active compound due to change in the equilibrium between two anomers, α and β is said to be mutarotation.
