Metabolomics studies the relationship between metabolite changes and phenotypes in living organisms under certain physiological conditions or in response to external stimuli in order to understand the underlying mechanisms of disease occurrence and development.

Metabolomics can act as a link between genetics and environmental exposures, revealing the origins of phenotypes in different people. Metabolite perturbation can more sensitively respond to changes in organism state and phenotypic differences, and is the most direct molecular basis for macroscopic phenotypic changes.

Metabolites are found in all types of biological samples, and the basic metabolic pathways are shared by even the most dissimilar species. Metabolomics research focuses not only on all metabolites in the body, but also on the various factors that regulate metabolism. As a result, metabolomics is appropriate for related research and applications involving the human body, food consumed by the human body, and microorganisms that interact with the human body.
