The mysteries of nitrogen balance [PDF]
Nutrition Research Reviews, 1999 AbstractThe first part of this review is concerned with the balance between N input and output as urinary urea. I start with some observations on classical biochemical studies of the operation of the urea cycle. According to Krebs, the cycle is instantaneous and automatic, as a result of the irreversibility of the first enzyme, carbamoyl-phosphate ...
