Description
Proceeding from 15N analyses, 15N tracer methods, and a model of protein metabolism it is shown that the nitrogen balance is a useful concept for expressing the relationship between the overall nitrogen intake of the body and the nitrogen excretion. After admistering low doses of 15N-labelled substances like protein and amino acids, the kinetics of digestion and absorption can be followed by measuring the 15N abundance in serum and urine of patients. A significant delay in the nitrogen absorption indicates gastrointestinal disorders
