Exotic phenomena in the
deterministic model of complex chemical reactions are studied on the basis of
preliminarily reported results. It is shown that the absence of a special kind
of autocatalysis, autoinhibition and cooperativity implies the existence of a
unique, asymptotically stable, positive equilibrium point. The class of
chemical reactions with gradient system as its deterministic model is
delineated. A procedure is given for the construction of oscillatory reactions.
A neurobiological application of one of the constructed models is shown.
