Which one is simple protein

Options

A. Albumin
B. Nucleoprotein
C. Lipoprotein
D. Glycoprotein.

Answer

To determine which option is a simple protein, we can follow these steps:

### Step 1: Understand the Definition of Simple Proteins
Simple proteins are those that yield only amino acids upon hydrolysis. They do not have any non-protein components attached to them.

**Hint:** Look for proteins that do not contain additional groups like carbohydrates or lipids.

### Step 2: Analyze the Given Options
The options provided are:
1. Albumin
2. Nucleoprotein
3. Lipoprotein
4. Glycoprotein

**Hint:** Consider the structure of each protein and whether they contain additional components.

### Step 3: Identify Each Protein Type
- **Albumin**: This is a globular protein found in egg whites. It is soluble in water and consists mainly of amino acids. Upon hydrolysis, it yields only amino acids.

- **Nucleoprotein**: This type of protein contains nucleic acids (DNA or RNA) as a prosthetic group.

- **Lipoprotein**: This protein type is combined with lipids, making it a conjugated protein.

- **Glycoprotein**: This protein contains carbohydrates (sugars) attached to it, classifying it as a conjugated protein.

**Hint:** Identify which of these proteins does not have any additional components attached.

### Step 4: Conclusion
Since albumin yields only amino acids upon hydrolysis and does not have any non-protein components, it is classified as a simple protein. The other options (nucleoprotein, lipoprotein, glycoprotein) are all conjugated proteins due to their additional components.

**Final Answer:** The simple protein among the options is **Albumin**.
