Which one of the following glycosidic linkage is found in maltose ?

Options

A. `beta` - 1 , 4
B. `alpha` - 4 , 1
C. `beta`,- 4 , 1
D. `alpha` -1,4

Answer

To determine the glycosidic linkage found in maltose, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Glycosidic Linkage**: Glycosidic linkage is a type of covalent bond that joins two carbohydrate molecules. It is formed between the hydroxyl group of one sugar and the anomeric carbon of another sugar.

2. **Identify Maltose**: Maltose is a disaccharide, which means it is composed of two monosaccharide units. In the case of maltose, these units are two alpha-D-glucose molecules.

3. **Determine the Type of Linkage**: The glycosidic linkage in maltose is specifically between the first carbon (anomeric carbon) of one glucose molecule and the fourth carbon of the other glucose molecule.

4. **Specify the Linkage Type**: The linkage formed between the two glucose units in maltose is known as an alpha-1,4 glycosidic linkage. This indicates that the bond is formed from the first carbon of one glucose (alpha configuration) to the fourth carbon of the other glucose.

5. **Select the Correct Option**: Given the options provided, the correct glycosidic linkage found in maltose is **alpha-1,4**.

### Final Answer:
The glycosidic linkage found in maltose is **alpha-1,4**.
