to test the hypothesis that a significant proportion of apolipoprotein ai ( apoai ) metabolism occurs through glomerular filtration of free apoai in serum and subsequent renal tubular metabolism , we have examined the urine concentration of apoai in three situations in which proximal tubular reabsorption of another protein metabolized in this manner and retinol-binding protein ( rbp ) was impaired .
