The storage protein in animal is

Options

A. haemoglobin
B. keratin
C. glutelin
D. elastin

Answer

To determine the storage protein in animals, we need to analyze the options provided:

1. **Hemoglobin**: This protein is found in red blood cells and is responsible for transporting oxygen throughout the body. It is not a storage protein, so this option is incorrect.

2. **Keratin**: Keratin is a structural protein that forms the basis of hair, nails, claws, and the outer layer of skin. It does not serve as a storage protein, making this option incorrect as well.

3. **Glutelin**: This is a storage protein typically found in plants, particularly in the seeds of the grass family, such as rice. While it is a storage protein, it is not specifically an animal storage protein, so this option is misleading in the context of the question.

4. **Elastin**: Elastin is a protein found in connective tissues that allows them to stretch and return to their original shape. It is not a storage protein, so this option is also incorrect.

After evaluating all the options, it appears that none of them correctly identify a storage protein specific to animals. However, the question may have intended to refer to proteins like **casein** (found in milk) or **myoglobin** (found in muscle tissue), which serve as storage proteins in animals.

### Final Answer:
The storage protein in animals is not explicitly listed in the options provided. However, common storage proteins in animals include **casein** and **myoglobin**.
