Maltose on hydrolysis gives

Options

A. Mannose + glucose
B. Galactose + glucose
C. Glucose
D. Mannose + fructose

Answer

To solve the question "Maltose on hydrolysis gives", we can follow these steps:

### Step 1: Understand the Structure of Maltose
Maltose is a disaccharide composed of two glucose units. Specifically, it consists of two alpha-D-glucose molecules linked together by an alpha-glycosidic bond.

### Step 2: Identify the Hydrolysis Process
Hydrolysis is a chemical reaction that involves the breaking of a bond in a molecule using water. In the case of maltose, the alpha-glycosidic bond between the two glucose units will be broken.

### Step 3: Apply Hydrolysis to Maltose
When maltose undergoes hydrolysis, water (H₂O) is added. The reaction can be summarized as follows:
- The glycosidic bond breaks.
- One glucose unit receives a hydrogen atom (H) from water.
- The other glucose unit receives a hydroxyl group (OH) from water.

### Step 4: Determine the Products
After hydrolysis, we are left with two molecules of alpha-D-glucose. Therefore, the products of the hydrolysis of maltose are:
- 2 molecules of alpha-D-glucose.

### Final Answer
On hydrolysis, maltose gives 2 units of alpha-D-glucose.
