Figure 6From: Estimation of the number of extreme pathways for metabolic networksRelationship between Reactions with Non-zero Clustering-coefficient and Alternative Routes. Diagram showing relationship between non-zero clustering coefficients and alternative pathways. (i) shows three possible routes for a simple system; (ii) is the non-directed representation of this system using the above projection. The system has non-zero clustering coefficients, emphasizing alternative routes are possible; (iii) is the projection conforming to that shown in Figure 5, where non-zero clustering coefficient is found for 5 of the reactions that are involved in the branching points of alterative routes.Back to article page
