Coproduct autocontrol

Luo and Epstein (1990) identified three types of negative feedback. The most common one in chemical oscillators is referred to as coproduct autocontrol. In this type of negative feedback, the positive feedback step, generally autocatalysis, generates not only more of the autocatalyst, but also a second product, or coproduct. This latter species reacts, either directly or indirectly, in such a way as to remove the autocatalyst and ultimately to shut down the autocatalysis. This pattern can be seen in the Oregonator (Field and Noyes, 1974b) ... 

Coproduct autocontrol is the dominant form of negative feedback in mechanisms for the copper-catalyzed hydrogen peroxide-thiocyanate (Luo et al., 1989), benzaldehyde autoxldatlon (Colussl et al., 1991), and bromate-iodlde (Citrl and Epstein, 1986) oscillators.
