Chapter 20, Problem 20.77CP

Interpretation Introduction

Interpretation:

The raffinose formed by the $\text{α-1,6-glycosidic}\text{linkage}$ of $\text{D-galactose}$ to the glucose portion of sucrose have to be drawn.

Concept introduction:

Glycosidic linkage forms raffinose by reaction of the $–OH$ group on the anomeric carbon of one monosaccharide with an $–OH$ group of a second monosaccharide, the naming of linkage is according to the number of the carbon at which the linkage begins and the carbon on the second monosaccharide at which the linkage ends.

Raffinose formed by the $\text{α-1,6-glycosidic}\text{linkage}$ of $\alpha \text{-D-galactose}$ to the glucose portion of sucrose.
