A glycosidic β 1->4 linkage involves a condensation reaction between a β1 OH on sugar A and an α4 OH on sugar B. A) True B) False

Understand the Problem

The question is asking to determine whether the statement about a glycosidic β 1->4 linkage is true or false. The key concepts involve the structural properties of sugars and the types of reactions involved in forming glycosidic linkages.

More Information

A β 1->4 linkage specifically involves the β1 OH group forming a bond with the 4th carbon OH group of another sugar, not the α4 OH on sugar B as suggested. Glycosidic bonds in disaccharides form by connecting equivalent OH groups either as α or β configuration.

Tips

Confusing the orientation and specific linkage sites between carbons, such as β and α linkages, is a common mistake.
