Figure 8From: Flux-sum analysis: a metabolite-centric approach for understanding the metabolic networkSummary of metabolite classification. The numbers of metabolites in each category is shown in brackets. The abbreviations "E" and "NE" denote essential and nonessential metabolites respectively. "AC","BC", "CC" and "AE", "BE", "CE" refer to the types of metabolites identified in flux-sum intensification and attenuation analyses respectively.Back to article page
