The metabolism of 4-pentenoate in isolated kidney tubules has been investigated by 1H and 13C NMR. The 4-pentenoate metabolite, 3-keto-4-pentenoyl-CoA, accumulated in proximal tubules only and its formation could be competitively inhibited by octanoate. 4-Pentenoate was metabolized in thick ascending

Fanconi's syndrome was investigated using brush border membrane (BBM) vesicles isolated from dog kidney. Sodium-dependent uptake of glucose, phosphate, and amino acids and protein phosphorylation were studied in BBM isolated from normal and from 4-pentenoate- and maleate-treated animals. The time

Isolated from pig liver as a crude, inhomogeneous enzyme fraction, pig liver esterase (PLE) was found to metabolize a wide range of substrates; often in a highly stereoselective manner. This crude esterase preparation, however, contains several iso-enzymes at proportions varying
