Hydrolysis of proteins give

Options

A. `alpha`-amino acid only
B. `beta`-amino acids only
C. `gamma`-amino acids only
D. mixture of all i.e. `alpha , beta` and `gamma`-amino acids

Explanation

**Step-by-Step Solution:**

1. **Understanding Proteins:**
- Proteins are large biomolecules made up of smaller units called amino acids. They are classified as macromolecular polymers, specifically composed of alpha amino acids linked together by peptide bonds.

2. **Definition of Hydrolysis:**
- Hydrolysis is a chemical process that involves the breakdown of a compound by reaction with water. In the case of proteins, hydrolysis breaks the peptide bonds between amino acids.

3. **Products of Protein Hydrolysis:**
- When proteins undergo hydrolysis, they are broken down into their constituent amino acids. The type of amino acids produced from protein hydrolysis is specifically alpha amino acids.

4. **Characteristics of Alpha Amino Acids:**
- Alpha amino acids are characterized by having both an amino group (-NH2) and a carboxyl group (-COOH) attached to the same carbon atom (the alpha carbon). Examples include glycine and alanine.

5. **Conclusion:**
- Therefore, the hydrolysis of proteins yields only alpha amino acids.

**Final Answer:**
- The hydrolysis of proteins gives alpha amino acids.
