Which of the following will have only amino acids as its end product

Options

A. Simple proteins
B. Conjugated proteins
C. Derived proteins
D. Globular proteins

Answer

To determine which of the given options will have only amino acids as its end product, we need to analyze each type of protein mentioned in the options:

1. **Simple Proteins**:
- Simple proteins are composed solely of amino acid subunits.
- These amino acids are linked together by peptide bonds.
- When simple proteins undergo hydrolysis (a reaction with water, often catalyzed by enzymes), they break down into their constituent amino acids.
- Examples include albumins and globulins.
- Therefore, simple proteins yield only amino acids as their end products.

2. **Conjugated Proteins**:
- Conjugated proteins consist of amino acids and additional non-polypeptide components (such as carbohydrates or lipids).
- When they are broken down, they yield not only amino acids but also these non-polypeptide groups.
- Thus, conjugated proteins do not produce only amino acids.

3. **Derived Proteins**:
- Derived proteins are modifications of simple or conjugated proteins.
- They are formed through processes such as denaturation or hydrolysis of simple proteins.
- The end products of derived proteins are not solely amino acids, as they may contain modified forms of proteins or other derivatives.

4. **Globular Proteins**:
- Globular proteins are a category of proteins that are generally water-soluble and have a spherical shape.
- They can be composed of both simple and conjugated proteins.
- The breakdown of globular proteins does not exclusively yield amino acids.

Based on this analysis, the correct answer is **Simple Proteins**, as they are the only type that yields only amino acids as their end product.

### Summary of the Solution:
- The correct answer is **Simple Proteins**.
- Simple proteins are made up entirely of amino acids and yield only amino acids upon hydrolysis.
- Other types of proteins (conjugated, derived, and globular) yield additional non-amino acid products.
