Albumin is a type of

Options

A. Fibrous protein
B. Globular protein
C. Lipid
D. Carbohydrate

Answer

**Step-by-Step Solution:**

1. **Identify the Type of Molecule:**
- The question asks about "albumin," which is a type of biomolecule. We need to determine what category it falls into among the given options: fibrous protein, globular protein, lipid, or carbohydrate.

2. **Understand the Properties of Albumin:**
- Albumin is a protein that is known to be water-soluble. This characteristic is crucial in identifying its type.

3. **Differentiate Between Protein Types:**
- There are two main types of proteins: fibrous proteins and globular proteins.
- **Fibrous Proteins:** These are typically long, insoluble in water, and serve structural roles (e.g., collagen, keratin).
- **Globular Proteins:** These are generally spherical in shape, soluble in water, and perform various functions such as enzymes and transport proteins.

4. **Classify Albumin:**
- Since albumin is described as water-soluble, it fits the definition of a globular protein. It has a globe-like structure and is involved in various physiological functions.

5. **Function of Albumin:**
- Albumin is the most common blood protein, produced by the liver. Its primary functions include maintaining osmotic pressure in the blood, providing nourishment to tissues, and acting as a carrier for hormones, vitamins, and minerals.

6. **Conclusion:**
- Based on the properties and functions of albumin, we conclude that albumin is classified as a globular protein. Therefore, the correct answer is "globular protein."

**Final Answer:**
Albumin is a type of globular protein.
