Background: Reaction networks (RNs) comprise a set X of species and a set R of reactions Y → Y ′, each converting a multiset of educts Y ⊆ X into a multiset Y ′ ⊆ X of products. RNs are equivalent to directed hypergraphs. However, not all RNs necessarily admit a chemical interpretation. Instead, they might contradict fundamental principles of physics such as the conservation of energy and mass or the reversibility of chemical reactions. The consequences of these necessary conditions for the…

The steady state entropy production rate is decompose in terms of fundamental fluxes and affinities in the spirit of Schnakenberg's theory of network thermodynamics, paving the way for the forthcoming treatment of the linear regime, of efficiency and tight coupling, of free energy transduction, and of thermodynamic constraints for network reconstruction.

A Graph-Based Toy Model of Chemistry

A Toy Model is presented that provides a consistent framework in which generic properties of extensive chemical reaction networks can be explored in detail and that at the same time preserves the "look-and-feel" of chemistry.

Multiple Equilibria in Complex Chemical Reaction Networks: II. The Species-Reaction Graph

- ChemistrySIAM J. Appl. Math.
- 2006

A new graph-theoretical method is suggested for discriminating between complex reaction networks that can admit multiple equilibria and those that cannot, which associates with each network a species-reaction graph, which is similar to reaction network representations drawn by biochemists.

Computational complexity of atomic chemical reaction networks

The computational complexity of deciding whether a given network is atomic according to each of these definitions is investigated and equivalence relationships between these definitions and some cases of an existing definition of atomicity due to Gnacadja are demonstrated.

It is concluded that the relation between distribution of dissipation, network topology and strength of disequilibrium is nontrivial and can be studied systematically by artificial reaction networks.

A unified view on bipartite species-reaction and interaction graphs for chemical reaction networks

A new definition of the species-reaction graph is presented that more directly connects the cycle structure with determinant expansion terms, principal minors, and the coefficients of the characteristic polynomial and encompasses previous graph constructions as special cases.

The search for a systems‐level picture of metabolism as a web of molecular interactions provides a paradigmatic example of how the methods used to characterize a system can bias the interpretation of…

On the Complexity of Reconstructing Chemical Reaction Networks

- MathematicsMath. Comput. Sci.

This paper addresses the problem of reconstructing a hypergraph from its species and reaction graph and shows NP-completeness of the problem in its Boolean formulation and studies the problem empirically on random and real world instances in order to investigate its computational limits in practice.

Properties of metabolic graphs: biological organization or representation artifacts?

- Computer ScienceBMC Bioinformatics
- 2010

The results combined suggest that the reported scaling of the clustering coefficients in the metabolic graphs and its specific power coefficient may be an artifact of the graph representation, and may not be supported when biochemical reactions are atomically treated as hyperedges.
