Applicants have discovered an efficient method for determining the rate of biosynthesis and / or degradation of biological molecules in a non-invasive manner. Disclosed herein is a method for determining the rate of biosynthesis or degradation of biological molecules from metabolic derivatives and catabolites. In particular, there is a method for measuring the rate of biosynthesis or degradation of biological molecules that are difficult or difficult to collect by direct sampling, by sampling metabolic derivatives and catabolic products in a collectable biological sample. , Disclosed herein. |
