To determine which of the options listed is not a lipid, let's analyze each choice:

1. **Cholesterol**: This is a type of lipid, specifically a sterol, which plays a significant role in cell membrane structure and function.

2. **Ribosome**: Ribosomes are not lipids; they are molecular machines in the cell composed of ribosomal RNA (rRNA) and proteins. Their primary function is to synthesize proteins from amino acids.

3. **Fat**: Generally refers to triglycerides, which are a class of lipids that serve as energy storage and are important for various biological functions.

4. **Fatty Acid**: Fatty acids are the building blocks of many lipids and are essential components of lipids like triglycerides and phospholipids.

### Conclusion
Based on this analysis, the correct answer is **ribosome**, as it is not a lipid.
