Popis: The virtual importance of the urea circuit is not clear. After a 3 to 21 day application of 100 mg [15N]-urea/l in 15 infants a [15N]-excess value of 0.06 in serum protein could be proven. Taking as a basis a protein content of 11.4% of the body mass and a regular distribution of the [15N] within the body one can calculate a retention of the urea nitrogen in the protein pool of 40.4% of the intake. Taking in account an amount of 11.4% urea nitrogen from the total nitrogen in mother's milk then the amount of urea nitrogen from the net protein accumulation comes to 6.5 (3.1-11.8)%.
