What is a glycoside linkage ?

Text Solution

AI Generated Solution

**Step-by-Step Solution:** 1. **Definition of Glycosidic Linkage:** A glycosidic linkage is a type of covalent bond that connects two monosaccharides (simple sugars) together. This bond is formed through an oxygen atom and involves the elimination of a water molecule. 2. **Formation of Glycosidic Linkage:** When two monosaccharides come together, one of the monosaccharides will provide a hydroxyl group (-OH) while the other provides a hydrogen atom (H). The combination of these two results in the removal of a water molecule (H2O), leading to the formation of the glycosidic bond. ...
