[{'content': 'Products of complete hydrolysis of cardiolipin are: \nSelect and explain. \nA. 3 glycerol, 4 fatty acids , 2 phosphates, B. 3 glycerol, 4 fatty acids , 1 phosphates, C. 3 glycerol, 3 fatty acids , 2 phosphates, D. 5 glycerol, 4 fatty acids , 2 phosphates', 'role': 'user'}, {'content': 'Answer: A \nExplanation: 3 glycerol, 4 fatty acids , 2 phosphates Cardiolipin is a complex phospholipid, which can be antigenic. The structure is glycerol attached to two phosphatidic acids. Each phosphatidic acid contains one glycerol, 2 FA and one phosphate. So in total 3 glycerol, 4 fatty acids, 2 phosphates are present in cardiolipin.', 'role': 'assistant'}]
