Bond between glycerol and fatty acid is :-

The correct Answer is:A

To answer the question regarding the bond between glycerol and fatty acid, we can follow these steps:

1. Identify the Components:
- Glycerol is a trihydroxy alcohol, specifically known as trihydroxypropane. It has three hydroxyl (–OH) groups.
- Fatty acids are carboxylic acids with long hydrocarbon chains, typically represented as R1COOH, where R1 is a long alkyl group.

2. Understand the Reaction:
- When glycerol and fatty acids combine, they undergo a dehydration reaction. This means that a water molecule (H2O) is removed during the process of bond formation.

3. Formation of the Ester Bond:
- In the dehydration synthesis, the hydroxyl group (–OH) from glycerol and a hydrogen atom (H) from the fatty acid are removed, leading to the formation of a bond between the two molecules.
- This bond that forms between the glycerol and the fatty acid is called an ester bond.

4. Conclusion:
- Therefore, the bond between glycerol and fatty acid is an ester bond.

Final Answer:
The bond between glycerol and fatty acid is called an ester bond.
