(8) Its bimetallic construction is similar to the existing £2 coin.
(9) Here, I report the effects of proton-motive force and membrane potential on two equilibria involving intermediates of the bimetallic centre at different levels of O2 reduction.

(11) As to the proteins whose redox potential is not facilitative and appreciably higher than -0.33 V, a bimetallic, concerted, two-equivalent reduction of the bound dioxygen to the peroxide level would be much more favoured without the intermediate formation of O2-.
(12) Analysis suggests that the two rapid reaction phases represent internal electron redistributions between the bimetallic site and cytochrome a, and between cytochrome a and CuA, respectively.
(13) At a high redox potential (Eh) of cytochrome c, high pH, and a high electrochemical proton gradient (delta mu H+) across the inner mitochondrial membrane, the initial ferriccupric state (O) of the oxidized enzyme's bimetallic oxygen reaction center is converted to ferryl (F) and peroxy (P) intermediates, the optical spectroscopic properties of which are reported in detail.
(14) In this evolution of special importance were bimetallic enzymes, such as nitrogenase, some nitrate reductases and hydrogenases, carbon dioxide reductase, xanthine oxidase, cytochrome oxidase.
(15) During respiration, an exogenous donor, cytochrome c, donates four electrons to O2 bound at the bimetallic haem alpha 3 Fe-Cu centre within the enzyme.
(16) The effect of different sodium chloride concentrations on the integrated currents (charge transfers) between dental amalgams and a gold alloy was studied in a bimetallic cell containing saliva or saline solutions.
(17) This is considerably slower than the maximal rates observed for electron transfer between cytochrome a and the bimetallic site found in earlier work and suggests rate limitation by other processes.
(18) The bimetallic haem iron-copper reaction centre in this family of enzymes is the critical structure for catalysis of both these processes.
(19) The bimetallic super-coiling might contribute to the power-stroke.
(20) Interestingly, in these circumstances (azide and uncoupler present), Fea behaves as if it were no longer the kinetically controlling electron donor to the bimetallic center.
Gold
Definition:
(n.) Alt. of Goolde
(v. t.) A metallic element, constituting the most precious metal used as a common commercial medium of exchange. It has a characteristic yellow color, is one of the heaviest substances known (specific gravity 19.32), is soft, and very malleable and ductile. It is quite unalterable by heat, moisture, and most corrosive agents, and therefore well suited for its use in coin and jewelry. Symbol Au (Aurum). Atomic weight 196.7.
(v. t.) Money; riches; wealth.
(v. t.) A yellow color, like that of the metal; as, a flower tipped with gold.
(v. t.) Figuratively, something precious or pure; as, hearts of gold.
