A Skeleton of four interlocking carbon rings is found in

Options

A. steroids
B. waxes
C. fats
D. glycerol

Answer

To solve the question "A skeleton of four interlocking carbon rings is found in," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure**: The question mentions a "skeleton of four interlocking carbon rings." This indicates a specific molecular structure that is characteristic of certain biomolecules.

2. **Identifying the Options**: The options provided in the video transcript include steroids, waxes, fats, and glycerol. We need to determine which of these contains the described structure.

3. **Analyzing Steroids**: According to the transcript, steroids have a core structure made up of 17 carbon atoms arranged in four fused rings. This structure consists of three six-membered cyclohexane rings and one five-membered cyclopentane ring.

4. **Comparing with Other Options**:
- **Waxes**: Waxes are long-chain fatty acids and alcohols but do not have a ring structure.
- **Fats**: Fats are typically triglycerides, which consist of glycerol and fatty acids, and do not contain interlocking carbon rings.
- **Glycerol**: Glycerol is a simple polyol compound and does not have a ring structure.

5. **Conclusion**: Since steroids are the only biomolecules listed that contain the specific structure of four interlocking carbon rings, we can conclude that the answer to the question is **steroids**.

### Final Answer:
The skeleton of four interlocking carbon rings is found in **steroids**.
