Studies of renal urea cycle enzymes. I. Renal concentrating ability and urea cycle enzymes in the rat during protein deprivation.


Activities of renal urea enzymes were studied in normally fed (21% dietary protein) rats and rats deprived of protein (6% dietary protein) for 3 weeks. Protein deprivation resulted in growth retardation and defective urine concentrating ability. Compared to rats on an optimal diet containing 21% of protein, the protein starved animals had decreased… (More)
