The correct answer to the above question is: Fats travel in lipoprotein carrier. They convey for the most part fats as triglycerides. In lipoproteins. Cholesterol is insignificantly solvent in water; it can't break up and travel in the water-based circulatory system. Rather, it is transported in the circulation system by lipoproteins that are water-dissolvable and convey cholesterol and triglycerides inside.
