The correct Answer is:
**Step-by-Step Solution:**
1. **Understanding Chylomicrons**: Chylomicrons are a type of lipoprotein that play a crucial role in the transport of dietary lipids from the intestines to other locations in the body.
2. **Formation of Chylomicrons**: After the digestion of fats, the breakdown products (fatty acids and monoglycerides) are absorbed by intestinal cells. Inside these cells, they are re-esterified (recombined) and then packaged with proteins to form chylomicrons.
3. **Composition of Chylomicrons**: Chylomicrons are primarily composed of triglycerides (fats) and are coated with proteins. This protein coating is essential for their transport in the lymphatic system.
4. **Size of Chylomicrons**: Chylomicrons are relatively large compared to other lipoproteins, measuring about 150 micrometers in diameter.
5. **Transport Mechanism**: Once formed, chylomicrons are released into the lymphatic system, specifically into small lymph vessels that eventually combine to form larger vessels called lacteals.
6. **Conclusion**: Based on the characteristics and functions of chylomicrons, the correct answer to the question is that they are "small fat globules coated with protein."
**Final Answer**: Chylomicrons are small fat globules coated with protein.
