Which of the following statements are incorrect about chylomicrons?
(i) Chylomicrons are produced in the epithelial cells of small intestine.
(ii) It contains trigycerides, cholesterol and phospholipids.
(iii) They are protein coated small vesicles.
(iv) Chylomicrons are released from the epithelial cell into lacteals

Options

A. i and iv
B. ii and iii
C. i,ii,iii and iv
D. none of these

Answer

To determine which statements about chylomicrons are incorrect, let's analyze each statement one by one:

1. **Statement (i): Chylomicrons are produced in the epithelial cells of the small intestine.**
- **Analysis:** This statement is correct. Chylomicrons are indeed produced in the epithelial cells (enterocytes) of the small intestine after the digestion of dietary fats.

2. **Statement (ii): It contains triglycerides, cholesterol, and phospholipids.**
- **Analysis:** This statement is also correct. Chylomicrons are composed of triglycerides, cholesterol, phospholipids, and fat-soluble vitamins.

3. **Statement (iii): They are protein-coated small vesicles.**
- **Analysis:** This statement is correct as well. Chylomicrons are lipoprotein particles, meaning they have a protein coat that surrounds the lipid core.

4. **Statement (iv): Chylomicrons are released from the epithelial cell into lacteals.**
- **Analysis:** This statement is correct. Chylomicrons are released from the epithelial cells into the lymphatic system, specifically into the lacteals, which are small lymph vessels in the intestine.

**Conclusion:** All four statements about chylomicrons are correct. Therefore, there are no incorrect statements among the options provided.

### Final Answer:
None of the statements are incorrect about chylomicrons.
