Q. 13.75 伪-Cellobiose is a disaccharide ... [FREE SOLUTION]

Chapter 13: Q. 13.75 (page 467)

$伪$ -Cellobiose is a disaccharide obtained from the hydrolysis of cellulose. It is quite similar to maltose except it has a $尾 (1 鈫� 4)$ -glycosidic bond. Draw the Haworth structure for $伪 -$ cellobiose. (13.4, 13.6)

$伪$ -Cellobiose is a disaccharide obtained from the hydrolysis of cellulose. It is quite similar to maltose except it has a role="math" localid="1652801603397" $尾 (1 鈫� 4)$ -glycosidic bond.

Step by step solution

Introduction

When cellulose is hydrolyzed, $伪$ -cellobiose is formed. It is a disaccharide with structural similarities to maltose except it has a $尾 - (1 - 4)$ -glycosidic bond instead of $伪 - (1 - 4)$ .
In this problem, we have to draw the structure of $伪 -$ -cellobiose in the Howarth projection.

Draw the structure of glucose in the Howarth projection.

Both maltose and cellobiose are formed from two molecules of glucose, but the difference is only in glycosidic bond formed from anomeric carbon (carbon produced from the open-chain version of the carbohydrate molecule's carbonyl carbon component).

Draw the structure of Maltose in the Howarth projection.

We know maltose, whose structure is shown in the Figure below has $伪$ - 1,4 -glycosidic (anomeric OH group opposite from ${CH}_{2} OH$ , and the only difference from cellobiose is the glycosidic bond.

Draw the Haworth structure for αcellobiose.

Knowing the structure of maltose, we can draw the structure of $伪$ -cellobiose, only changing the glycosidic bond from $伪$ to $尾 - 1, 4$ .
