Adipic acid | C6H10O4 - PubChem

Radioactive ,adipic acid, was fed to fasted experimental rats and the metabolic products identified in the urine were urea, glutamic acid, lactic acid, beta-ketoadipic acid, and citric acid.The presence of beta-ketoadipic acid provided some evidence that ,adipic acid, is metabolized by beta-oxidation in much the same fashion as fatty acids. Further evidence was provided by the appearance of ...
