Impaired interaction of metabolic pathways plays a significant role in disease pathogenesis. Measurement of pathway metabolites and metabolite fluxes completed by mathematical modelling identifies genetic determinants and modifiers such as the microbiome or antibiotics. “Thinking in metabolic networks“ has also become essential for the understanding of monogenic metabolic diseases.
