[{'content': 'Main lipid component of chylomicrons is \nSelect and explain. \nA. Triacylglycerols, B. Phospholipids, C. Cholesterol, D. Free fatty acids', 'role': 'user'}, {'content': 'Answer: A \nExplanation: Plasma lipids consist of triacylglycerols (16%), phospholipids (30%), cholesterol (14%), and cholesteryl esters (36%) and a much smaller fraction of unesterified long-chain fatty acids (free fatty acids or FFA) (4%). The FFA is metabolically the most active of the plasma lipids.
