Which of the following is not a function of liver:

Options

A. Deamination
B. Bile storage
C. Synthesis of plasma protein
D. Storage of fat soluble vitamin

Answer

To determine which of the following is not a function of the liver, we will analyze the functions of the liver based on the provided information.

### Step-by-Step Solution:

1. **Understand the Functions of the Liver**:
- The liver is involved in several metabolic processes including carbohydrate metabolism, lipid metabolism, and protein metabolism.
- It plays a crucial role in maintaining blood glucose levels, storing fats, and processing proteins.

2. **List the Functions of the Liver**:
- **Carbohydrate Metabolism**: Helps maintain normal blood glucose levels.
- **Lipid Metabolism**: Stores fats and breaks them down for energy when needed.
- **Protein Metabolism**: Involves deamination of amino acids and synthesis of plasma proteins.
- **Synthesis of Bile**: The liver produces bile, which is important for digestion.
- **Storage of Vitamins and Minerals**: Stores fat-soluble vitamins (A, D, E, K) and minerals like iron and copper.
- **Processing of Drugs and Hormones**: Metabolizes various substances.
- **Phagocytosis**: Kupfer cells in the liver perform phagocytosis.

3. **Evaluate the Given Options**:
- **Deamination**: This is a function of the liver as part of protein metabolism.
- **Bile Storage**: This is NOT a function of the liver; bile is synthesized by the liver but stored in the gallbladder.
- **Synthesis of Plasma Proteins**: This is a function of the liver.
- **Storage of Fat-Soluble Vitamins**: This is also a function of the liver.

4. **Identify the Correct Answer**:
- Since bile storage is the only option that is not a function of the liver (it is stored in the gallbladder), the correct answer is **Bile Storage**.

### Conclusion:
The function that is not performed by the liver is **Bile Storage**.
