GLYCOSIDIC BOND Meaning and
Definition
-
A glycosidic bond refers to a type of covalent chemical bond that connects two sugar molecules by linking their anomeric carbon atom with another atom or functional group. It is a common form of linkage in organic chemistry and biochemistry, particularly in the formation of carbohydrates. This bond is formed through a condensation reaction between the hydroxy group (-OH) of one sugar molecule and the anomeric carbon of another sugar molecule. The resulting glycosidic bond eliminates a water molecule and forms a stable covalent bond.
Glycosidic bonds are essential for constructing different forms of carbohydrates, such as disaccharides, oligosaccharides, and polysaccharides. They determine the overall structure and function of these macromolecules by dictating their physical properties and biological activities. The type and configuration of the glycosidic bond vary based on the involved sugar molecules, resulting in dissimilar structures and properties.
The nomenclature of glycosidic bonds often includes a designation of the involved sugars and the specific carbon atoms involved in the linkage. For example, the α-1,4-glycosidic bond present in cellulose connects glucose molecules through their first carbon (anomeric carbon) and fourth carbon atoms. Similarly, lactose, a disaccharide composed of glucose and galactose, is connected by a β-1,4-glycosidic bond. By altering the type and position of the glycosidic bond, an extensive diversity of carbohydrates can be formed, which have numerous physiological functions in living organisms.

Etymology of GLYCOSIDIC BOND
The word "glycosidic bond" originates from the combination of two terms: "glycosidic" and "bond".
1. Glycosidic: This term is derived from "glycoside", which refers to a class of compounds consisting of a sugar molecule bonded to another functional group. The word "glycoside" comes from the French word "glycoside", coined by Charles-Adolphe Wurtz in 1847. It combines "glyco-" (derived from the Greek word "glýkys", meaning sweet) and "-ide" (a suffix used to indicate chemical compounds).
2. Bond: The term "bond" is a general term used in chemistry to describe a connection or linkage between atoms within a molecule. It is derived from the Old English word "bonda", meaning a binding or joining.
