For the cytochrome c-plastocyanin complex, the kinetic effects of cross-linking are much more drastic while the rate of the intracomplex transfer is equal to 1000 s in the noncovalent complex where the iron-to-copper distance is expected to be about 18 A, it is estimated to be lower than 0.2 s in the corresponding covalent complex [155]. This result is all the more remarkable in that the spectroscopic and thermodynamic properties of the two redox centers appear weakly affected by the cross-linking process, and suggests that an essential segment of the electron transfer path has been lost in the covalent complex. Another system in which such conformational effects could be studied is the physiological complex between tetraheme cytochrome and ferredoxin I from Desulfovibrio desulfuricans Norway the spectral and redox properties of the hemes and of the iron-sulfur cluster are found essentially identical in the covalent and noncovalent complexes and an intracomplex transfer, whose rate has not yet been measured, takes place in the covalent species [156].

Copper-dioxygen complexes are necessary intermediates in the biomimetic oxidations performed by type 3 Cu models. Several structural motifs for synthetic Cu 02 complexes exist and the main types are shown in Scheme 4. Their mechanism of formation, structural characteristics, spectroscopic and thermodynamic properties, and reactivity have been recently thoroughly reviewed (62,63). In general, the reaction between a Cu(I) complex and dioxygen initially forms a 1 1 Cu/02 adduct that, in the absence of steri-cally hindered ligands, rapidly evolves to the thermodynamically more stable 2 1 Cu/02 adduct. According to the usual formalism, these processes can be described by the following equilibria ... 

The compounds, derived from L-threonic acid and various biological metal elements, facilitate the combination of the metal ions with amino acids or proteins and improve the efficiencies of the absorption and utilization of these metal ions in the humw body. Qing and coworkers investigated the thermodynamic properties of copper L-threonate hydrate by adiabatic calorimetry and combustion calorimetry [158].

There are no observed phase changes or major discontinuities in the thermodynamic properties of nickel-copper alloys at 60-70% Cu, whereas chemisorption on any metal is known to be favored by an unfilled d-band configuration [48]. The good agreement, therefore, between observed and predicted critical... 

The thermodynamic properties of C-Cu-Fe dilute liquid alloys of system at 1600°C were compiled and evaluated by [1974Sig]. The frrst-order free energy interaction coefficients for the C-Cu-Fe melts at 1600°C showing the effect of copper on solubility of carbon in the melt and vice versa are 0.066 and -0.06, respectively (die composition was expressed in mass%).
