Free fatty acids are transpoed by : 
Select and explain. 
A. Ceruloplasmin, B. Pre-albumin, C. Albumin, D. Transthyretin
C: Albumin
Answer: C: Albumin 
Explanation: Free fatty acids are transpoed in the blood bound to albumin, a serum protein secreted by the liver. Most other lipids are transpoed in the blood as pa of complex paicles called lipoproteins.Lipoproteins differ in the ratio of protein to lipids, and in the paicular apoproteins and lipids that they contain. They are classified based on their density:Chylomicron (largest; lowest in density due to high lipid/protein ratio; highest in triacylglycerols as % of weight)VLDL (very low density lipoprotein; 2nd highest in triacylglycerols as % of weight) IDL (intermediate density lipoprotein)LDL (low density lipoprotein, highest in cholesteryl esters as % of weight)HDL (high density lipoprotein, highest in density due to high protein/lipid ratio).
