Bedford, J.J. | Smiley, M. | Leader, J.P.
The cortex, inner and outer medulla, and papilla of kidneys of domestic red deer were analysed. In hydrated animals the urine concentration was found to be 672 +/- 45 mOsm.l-1. The medullary and papillary regions of the kidney were rich in the osmolytes betaine, glycerophosphorylcholine (GPC), inositol and sorbitol, all of which showed a steep rise in concentration from cortex to papilla. The kidney was rich in free amino acids, in particular taurine, glutamate (+ glutamine), glycine and alanine, which were present at concentrations sufficient to suggest a possible role as osmolytes.
