Prolamines are
(a) Associated with nucleic acids
(b) Storage proteins
(c) Enzymatic protein
(d) Structural protein

Options

A. Associated with nucleic acids
B. Storage proteins
C. Enzymatic protein
D. Structural protein

Answer

To determine what prolamines are, let's analyze the options provided in the question step by step:

1. **Understanding Prolamines**: Prolamines are a specific group of proteins found in plants. They are primarily known for their role in storage within seeds.

2. **Identifying Characteristics**: Prolamines are characterized by:
- High content of proline and glutamine amino acids.
- Poor solubility in water.
- Their presence in cereal grains such as wheat, barley, rye, corn, and sorghum.

3. **Evaluating the Options**:
- **Option A: Associated with nucleic acids**: This is incorrect as prolamines are not primarily associated with nucleic acids.
- **Option B: Storage proteins**: This is correct. Prolamines serve as storage proteins in plants, especially in seeds.
- **Option C: Enzymatic protein**: This is incorrect as prolamines do not function as enzymes.
- **Option D: Structural protein**: This is also incorrect since prolamines do not provide structural support.

4. **Conclusion**: Based on the characteristics and the evaluation of the options, prolamines are classified as storage proteins.

Thus, the correct answer is **(b) Storage proteins**.
