Which vitamins are transported through the body by lipoproteins after absorption?

• A. Fat soluble vitamins
• B. Water soluble vitamins
• C. Both
• D. None

Answer: (A)

Fat-soluble vitamins rely on lipoproteins for their transport after absorption. Because they are fat-loving and not water-soluble, they’re absorbed with dietary fat and packaged into chylomicrons, which are lipoprotein particles that travel through the lymphatic system and into the bloodstream. This lipoprotein vehicle allows these vitamins to move through the watery blood and reach tissues or the liver for storage and distribution. Water-soluble vitamins, on the other hand, enter the portal circulation and mostly travel dissolved in plasma, often bound to specific carrier proteins, rather than riding on lipoproteins.
