Which of the following sugars cannot split into further groups by hydrolysis ?

Options

A. Glucose
B. Sucrose
C. Lactose
D. Maltose.

Answer

To determine which sugar cannot be split into further groups by hydrolysis, we need to understand the classification of sugars. Here’s a step-by-step solution:

### Step 1: Understand the Types of Sugars
- Sugars are classified into two main categories: monosaccharides and disaccharides.
- Monosaccharides are the simplest form of sugars and cannot be hydrolyzed into smaller sugars.
- Disaccharides are composed of two monosaccharide units and can be hydrolyzed into their respective monosaccharides.

### Step 2: Analyze the Given Options
- The options provided are:
1. Glucose
2. Sucrose
3. Lactose
4. Maltose

### Step 3: Identify Each Sugar Type
- **Glucose**: This is a monosaccharide. It cannot be hydrolyzed further because it is already in its simplest form.
- **Sucrose**: This is a disaccharide made up of glucose and fructose. It can be hydrolyzed into these two monosaccharides.
- **Lactose**: This is also a disaccharide composed of glucose and galactose. It can be hydrolyzed into these monosaccharides.
- **Maltose**: This disaccharide consists of two glucose units and can be hydrolyzed into glucose.

### Step 4: Conclusion
Based on the classification:
- Glucose is the only sugar in the list that cannot be split into further groups by hydrolysis because it is a monosaccharide. The other options (sucrose, lactose, maltose) can all be hydrolyzed into smaller sugars.

### Final Answer
The sugar that cannot split into further groups by hydrolysis is **glucose**.
