Which of the following is used in life saving substance as blood plasma

Options

A. Cellulose
B. Teflon
C. Bakelite
D. Poly vinyl pyrrolidone(PHBV)

Answer

To determine which of the given options is used in life-saving substances such as blood plasma, we will analyze each option step by step.

### Step 1: Analyze the options

1. **Cellulose**:
- Cellulose is a polysaccharide made up of glucose monomers (C6H10O5)n.
- It is primarily used in the production of paper and biofuels, and it does not have applications in blood plasma.

2. **Teflon**:
- Teflon is made from tetrafluoroethylene (C2F4) and is known for its non-stick properties.
- It is widely used in cookware and does not have any application in blood plasma.

3. **Bagalite**:
- Bagalite is a type of phenol-formaldehyde resin.
- It is used in electrical switches and handles, but it is not related to blood plasma.

4. **Polyvinylpyrrolidone (PVP)**:
- PVP is a water-soluble polymer made from the monomer N-vinylpyrrolidone.
- It is used as a plasma volume expander for trauma victims, making it relevant for blood plasma applications.

### Step 2: Conclusion

After analyzing all the options, the correct answer is **Polyvinylpyrrolidone (PVP)**, as it is specifically used as a plasma volume expander in medical applications.

### Final Answer:
**Polyvinylpyrrolidone (PVP)** is used in life-saving substances such as blood plasma.
