What is "fluxomics"

n. (context biology English) The study of the flow of fluid and molecules within cells

Fluxomics describes the various approaches that seek to determine the rates of metabolic reactions within a biological entity. While, metabolomics can provide instantaneous information on the metabolites in a biological sample, metabolism is a dynamic process. The significance of fluxomics is that metabolic fluxes determine the cellular phenotype. It has the added advantage of being based on the metabolome which has fewer components than the genome or proteome.

Fluxomics falls within the field of systems biology which developed with the appearance of high throughput technologies. Systems biology recognizes the complexity of biological systems and has the broader goal of explaining and predicting this complex behavior.
