Are you curious to know what is glycosidic linkage? You have come to the right place as I am going to tell you everything about glycosidic linkage in a very simple explanation. Without further discussion let’s begin to know what is glycosidic linkage?
In the intricate world of biochemistry, glycosidic linkage stands as a fundamental concept, playing a crucial role in the structure and function of various biomolecules. This article aims to provide a detailed understanding of what glycosidic linkage is, its types, examples, and its significance in the realm of chemistry, catering to both Class 11 and Class 12 levels.
What Is Glycosidic Linkage?
A glycosidic linkage is a covalent bond that connects two sugar molecules or a sugar molecule with a non-sugar compound. It is a pivotal structural element in carbohydrates, forming through the condensation reaction between the hydroxyl group of one sugar and the anomeric carbon of another.
What Is Glycosidic Linkage Class 11:
For Class 11 students delving into biochemistry, understanding glycosidic linkage lays the foundation for comprehending the complex structures and functions of carbohydrates. It serves as a connecting bridge between individual sugar units, contributing to the diversity of biological macromolecules.
What Is Glycosidic Linkage Class 12:
In Class 12, the study of glycosidic linkage advances, incorporating detailed insights into its role in polysaccharides, disaccharides, and other complex carbohydrates. The knowledge gained in Class 12 forms the basis for understanding intricate biochemical processes.
What Is Glycosidic Linkage In Chemistry:
From a chemical perspective, glycosidic linkage involves the formation of an acetal or ketal linkage between the anomeric carbon of one sugar molecule and the hydroxyl group of another. This reaction results in the elimination of water and the creation of a stable covalent bond.
What Is Glycosidic Linkage Example:
An illustrative example of glycosidic linkage is the formation of maltose from two glucose molecules. The linkage occurs between the anomeric carbon of one glucose and the hydroxyl group of the other, leading to the elimination of water and the creation of a glycosidic bond.
Types Of Glycosidic Linkage:
- Alpha Glycosidic Linkage: The hydroxyl group is below the plane of the sugar ring.
- Beta Glycosidic Linkage: The hydroxyl group is above the plane of the sugar ring.

1,6 Glycosidic Bond:
The 1,6 glycosidic bond is a specific type of linkage where the glycosidic bond forms between the carbon atoms at positions 1 and 6 of two sugar molecules. This bond is commonly found in branching points of polysaccharides like glycogen and amylopectin.
Glycosidic Linkage In Sucrose:
Sucrose, a disaccharide composed of glucose and fructose, features a glycosidic linkage between the anomeric carbon of glucose and the hydroxyl group of fructose. This linkage results in the formation of a sucrose molecule and the release of a water molecule.
Glycosidic Linkage In Maltose:
Maltose, another disaccharide, is formed by the glycosidic linkage between the anomeric carbon of one glucose molecule and the hydroxyl group of another glucose molecule. This alpha 1,4-glycosidic bond is central to the structure of maltose.
Glycosidic linkage, a cornerstone of biochemistry, intricately weaves the fabric of carbohydrates, essential biomolecules in living organisms. Whether studied at the Class 11 or Class 12 level, the understanding of glycosidic linkage unlocks the doors to comprehending the complex structures, functions, and interactions that define the biochemical landscape. From maltose to sucrose, the diverse examples of glycosidic linkage underscore its universal importance in the language of life sciences and chemistry.
What Do You Mean By Glycosidic Linkage?
Glycosidic linkage refers to the linkage formed between two monosaccharide units through an oxygen atom by the loss of a water molecule. For example, in a sucrose molecule, two monosaccharide units, ∝-glucose and β-fructose, are joined together by a glycosidic linkage.
What Is Meant By Glycosidic Bond?
A glycosidic bond, also known as a glycosidic linkage, is a chemical bond in the form of a covalent connection that connects a carbohydrate (sugar) molecule to another group, which might be another carbohydrate or not. The sugar group is referred to as a glycone, while the non-sugar group is referred to as an aglycone.
What Is The Glycosidic Linkage In Nad+?
Structurally, the NAD+ coenzyme can be viewed as a nicotinamide base in a β-glycosidic linkage with adenosine diphosphate (ADP)ribose. Hydride is transferred to and from the nicotinamide ring, such that the plus sign indicates a positive charge on the nitrogen ring.
What Is Glycosidic Linkage In Ncert?
The two monosaccharides are joined together by an oxide linkage formed by the loss of a water molecule. Such a linkage between two monosaccharide units through oxygen atom is called glycosidic linkage.
