In catabolic reactions, molecules are broken down, and energy is released.

In the field of metabolomics, nuclear magnetic resonance (NMR) spectroscopy is a highly valued technique because it is non-destructive. Unlike some other analytical methods that may require extensive sample preparation or chemical extraction, NMR preserves the integrity of both the metabolites and the biological specimens themselves.

Because the sample remains intact during the analysis, it can be recovered and investigated subsequently using other experimental techniques. This capability makes NMR a particularly efficient and reproducible tool for researchers who need to maximize the information gained from limited biological material.1
