The phenotype of an organism grown under defined environmental conditions may be characterized by the fluxes carried out at each individual reaction in the organism's metabolic network. Metabolic fluxes are nonmeasurable quantities, but they can be quantified using a combination of specific measurements and mathematical modelling.
