Substrate satisfaction condition for applying enzyme reactions. As a constraint for applying a reaction rule to a compound, the substrate inclusion condition is modeled by inclusion of the substrate vector. When attempting to apply the reaction rule R = (U, O) to a compound vector C, the compound vector C must include the substrate vector U as part of its own structure. That is, for any k, the value c k in the compound vector C = (c1, ..., c n ) must exceed the value u k in the substrate vector U = (u1, ..., u n ).
