Simple sugar of blood is -

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding Simple Sugars**:
- Simple sugars are also known as monosaccharides. They are the most basic form of carbohydrates and cannot be hydrolyzed into simpler sugars.

2. **Identifying the Simple Sugar in Blood**:
- The primary simple sugar found in the blood is glucose. It is a monosaccharide that serves as a key source of energy for the body.

3. **Role of Glucose in the Body**:
- Glucose is utilized by the body for energy. It is crucial for cellular respiration, where it is broken down to release energy.

4. **Storage of Glucose**:
- In the animal body, excess glucose is stored in the form of glycogen. This storage primarily occurs in the liver and skeletal muscles.

5. **Other Sugars**:
- Other sugars mentioned, such as dextrin, lactose, and sucrose, are not classified as simple sugars:
- **Dextrin**: A low molecular weight carbohydrate formed from the hydrolysis of glycogen.
- **Lactose**: A disaccharide composed of glucose and galactose.
- **Sucrose**: A disaccharide known as table sugar, formed from glucose and fructose.

6. **Conclusion**:
- Therefore, the simple sugar of the blood is glucose.

**Final Answer**: The simple sugar of blood is glucose.
