1 Define the terms glycoside and glycosidic bond.

Expert Solution
Interpretation Introduction

Interpretation:

The terms glycoside and glycosidic bond should be explained.

Concept Introduction:

Glycoside provides the hemiacetal group for the sugar. For example glucosides are glycosides formed by the glucose and fructoside from fructose. Therefore, if glucose gives the hemiacetal group, the molecule so formed is a glucoside and if galactose gives the hemiacetal group, the molecule so formed is a galactoside.

Explanation of Solution

When the hydroxyl group on the anomeric carbon of a sugar reacts with the hydroxyl group of another molecule glycosides are formed. This acetal or ketal linkage is known as a glycosidic bond. The formation of acetal is an example of glycosides formation...
