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.
