Chain length, maximal

The chain-terminating efficiency of inhibitors can be characterized by the chain length if - v/v (more potent inhibitors provide shorter chains). From Table 14.7, the inhibitory efficiency depends on the mechanism of oxidation of the reactants RH and InH at the ambient conditions (T, iy and the reactant concentrations). It can be seen from Table 14.7 that higher k7 values always correspond to lower v. Therefore, the most potent inhibitors are those that possess maximal k7. ... 

Walters and Olejnik s ( H) data on methyl nicotinate transfer through hairless mouse skin. All indicate maximal activity residing with the C22 ether. Not only do the latter two studies indicate a falling off in effectiveness as the chain length is increased to and Cia but they also indicate that the oleyl (unsaturated chain) ethers are more active than their saturated analogues. 

Effect of alkyl chain length in CmPOEn on the absorption spectra. The relationship between the absorption spectra and the mixed molar ratio of the SDS-C22l OE20 surfactant system is shown in Fig.l. The maximal absorption wavelength almost shifts to 450 nm with increasing the molar ratio of C] 2 20 absorption at... 

Some semi-quantitative confirmation of these A factors comes from the consideration that the pyrolysis of C2H8 at 900°K. is a chain reaction in which the data on maximal inhibition indicate a chain length X of the order of 10. Since the only likely homogeneous, initiation process is the fission of C2H8 into 2CH3, the hypothetical first-order rate constant for the pyrolysis can be set equal to this initiation rate constant multiplied by X ... 

As long ago as 1984, Lau et al.1311 demonstrated that stable coiled coils of four heptads in length could be formed. Subsequent work set out to examine the factors that would maximize stability of the coiled coil in the shortest possible chain length, for example, hydro-phobicity and packing effects in the hydrophobic core, intrachain electrostatic interactions, and the helical propensity contribution of residues outside the hydrophobic interface.123,24 30 321...
