Question

Chylomicrons are __________________.

• A. Fat droplets coated with phospholipids
• B. Fat droplets coated with cholesterol and protein
• C. Undigested proteins
• D. Undigested carbohydrates

Answer 1

The correct option is B Fat droplets coated with cholesterol and protein

• Fatty acids and glycerol being insoluble, cannot be absorbed into the blood. So, they are first incorporated into small droplets called micelles which move into the intestinal mucosa.
  
• They are then re-formed into very small protein coated fat globules called the chylomicrons which are transported into the lymph vessels (lacteals) in the villi. These lymph vessels ultimately release the absorbed substances into the bloodstream. Hence, chylomicrons are fat droplets coated with cholesterol and proteins.

So, the correct answer is 'fat droplets coated with cholesterol and proteins'.
