protein catabolic rate


Also found in: Dictionary, Encyclopedia.

protein catabolic rate (PCR)

a calculation derived by multiplying 6.25 times the amount of nitrogen in grams excreted in the urine over a given time period, which represents the amount of protein catabolized by the body in excess of protein synthesis. In a healthy steady state of nitrogen balance, it approximates the amount of protein in the diet.

In patients receiving hemodialysis, the quantity of urea that appears in the blood between two dialysis sessions—a function of the amino acid content of the patient's diet.
