Abundance of osmolytes. The results of the HPLC sample demonstrate the concentrations of five key osmolytes in the papilla and cortical regions of the kidney nephron. On almost all of these occasions the concentration of each osmolyte is greater in the papilla than in the cortex. This is consistent with research by Schmolke et al, 1991, where the distribution of total organic osmolytes was found to increase progressively form the outer cortex in towards the inner medullary regions of the papilla. …
