title: Urea cycle enzyme adaptation to dietary protein in primates.
abstract: Activities of the five hepatic enzymes of the urea cycle increased two- to threefold in monkeys on a 60 percent protein diet compared with levels in monkeys on an isocaloric 6 percent protein diet. Equal adaptation occurred in rats on the same diets. These enzyme activities in adult humans approximate those of monkeys on a similar protein intake.
