Glycerol 3-phosphate', 'role': 'user'}, {'content': 'Answer: D \nExplanation: Under metabolic conditions associated with a high rate of fatty acid oxidation, the liver produces considerable quantities of acetoacetate\xa0and\xa0 d(-)-3-hydroxybutyrate\xa0(β-hydroxybutyrate). Acetoacetate\xa0continually\xa0undergoes\xa0spontaneous\xa0decarboxylation\xa0to\xa0yield\xa0acetone.\xa0These\xa0three\xa0 substances\xa0are\xa0collectively known as the ketone bodies (also called acetone bodies or\xa0 \xa0 “ketones”).\nHARPERS ILLUSTRATED BIOCHEMISTRY30th ed Page no 226', 'role': 'assistant'}]
