In monoglycerides, glycerol attached with fatty acid molecule by which bond?

Answer

To answer the question, "In monoglycerides, glycerol is attached with fatty acid molecule by which bond?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Glycerol**: Glycerol is a simple polyol compound, specifically a trihydroxypropane, which means it has three hydroxyl (-OH) groups.

2. **Understanding Fatty Acids**: Fatty acids are long hydrocarbon chains with a carboxyl (-COOH) group at one end. They can vary in length and saturation.

3. **Formation of Monoglycerides**: Monoglycerides are formed when one fatty acid molecule is esterified to glycerol. This means that one of the hydroxyl groups of glycerol reacts with the carboxyl group of the fatty acid.

4. **Type of Bond Formed**: The bond that forms between the glycerol and the fatty acid during this reaction is called an **ester bond**. This occurs through a dehydration synthesis reaction, where a water molecule is released.

5. **Conclusion**: Therefore, in monoglycerides, glycerol is attached to the fatty acid molecule by an **ester bond**.

### Final Answer:
In monoglycerides, glycerol is attached to the fatty acid molecule by an **ester bond**.
