Which one yields protein on hydrolysis ?

Options

A. Fatty acid
B. Nucleic acid
C. Amino acid
D. None of the above.

Answer

To determine which option yields protein on hydrolysis, we need to analyze each option provided:

1. **Understanding Hydrolysis**: Hydrolysis is the chemical process in which water is used to break down a compound. In the context of biological molecules, hydrolysis typically involves breaking down larger macromolecules into their smaller building blocks.

2. **Analyzing the Options**:
- **Fatty Acids**: When fatty acids undergo hydrolysis, they do not yield proteins. Instead, they break down into glycerol and fatty acids. Therefore, this option is incorrect.
- **Nucleic Acids**: Upon hydrolysis, nucleic acids (like DNA and RNA) yield nitrogenous bases, pentose sugars, and phosphate groups. They do not yield proteins, making this option also incorrect.
- **Amino Acids**: Amino acids are the building blocks of proteins. They cannot be hydrolyzed to yield proteins because they are already the simplest form of protein. Thus, this option is incorrect as well.

3. **Conclusion**: Since none of the options (fatty acids, nucleic acids, or amino acids) yield proteins upon hydrolysis, the correct answer is **D: None of the above**.

**Final Answer**: D: None of the above
