68. The chemical reason why lipids cannot travel freely in blood plasma without being packaged into lipoprotein complexes is their

A. Unusually high molecular weight
B. Hydrophobic nature and total insolubility in aqueous environments
✓
C. High reactivity with circulating oxygen molecules
D. Tendency to undergo spontaneous hydrolysis into glucose

📝 Explanation

Non-polar triacylglycerols and cholesterol esters aggregate in water; lipoproteins shield them to allow smooth transport through the blood.
