Nodes	m	Quantity of metabolic compartments, also the size of network
Links	L	Quantity of metabolic direct flows or arcs
Link density	L/m	Metabolic linking degree
Connectance	L/m^2	Metabolic connectivity, also the proportion of realized direct pathways
MI	Equation (3)	Metabolic system
SI	Equation (4)	Metabolic system synergism
CI	Equation (9)	Self-regulation of metabolism
