Metabolic networks can be modeled as graphs, i.e., mathematical structures consisting of vertices (representing objects such as metabolites) and edges/hyperedges (representing the connection between objects such as reactions). An example of a very simple metabolic network is shown in Fig. 7.1. Often the term network refers to an informal concept describing a structure composed of objects and connections, whereas the term graph refers to an abstract mathematical structure formed by a set of vertices and a set of edges. For simplicity, we will consider both terms equivalent in the following.
