Relationships Between some Dissociation Constants
Nature, 1947IN these Laboratories the fungistatic properties of ethylenic and acetylenic compounds have been studied recently1. Our results indicated that biological activity was connected with the presence of substituents that attract electrons strongly, and led us to a consideration of the dissociation constants of compounds which donate protons (that is, acids ...

Dissociation constants and structure of ergothioneine
Analytical Biochemistry, 1964Abstract The structure of ergothioneine was studied from the dependence of ultraviolet spectra on pH and H0. This and the correlation with some model compounds strongly suggests that ergothioneine exists in the form of a dipolar betaine.

Dissociation constants of organophosphinic acid compounds
Talanta, 1993The dissociation equilibria of di(2,4,4-trimethylpentyi) phosphinic acid, mono(2,4,4-trimethylpentyl) phosphinic acid, di(n-octyl)phosphinic acid and mono(n-octyl)phosphinic acid have been studied in ethanol-water mixtures by potentiometric titration at 25 degrees C.

Potentiometric Determination of Overlapping Dissociation Constants
Journal of Pharmaceutical Sciences, 1973The dissociation constants of polyprotic acids can be determined potentiometrically by defining a variable, P, as the average number of protons dissociated. The proton balance equation for the titration of these acids with base led to a general expression which could be solved graphically or through the use of linear regression or nonlinear regression ...

Dissociation Constant I: Agonists
1987An agonist and an antagonist that act on the same receptor are used in this determination. The antagonist must bind irreversibly to the receptor; its presence, therefore, inactivates the receptors to which it combines. If the antagonist concentration is not too great, it will inactivate only a fraction of the total receptor pool and produce a ...

Degeneracy and Dissociation Constants
Nature, 1940THE importance of degeneracy in enhancing the stability of radicals such as triphenylmethyl has been emphasized by many authors; for example, Pauling and Wheland1, Ingold2, etc. This being so, it is strange that no relations have been suggested between complexity of degeneracy (which we may define in terms of the number of possible resonating ...

Dissociation constants of some organic acids
Talanta, 1984Dissociation constants of di(nonylphenyl)dithiophosphoric acid, di(nonylphenyl)phosphoric acid and 9-phenyltetracosansulphuric acid, determined by two methods, are reported.

Dissociation Constant II: Partial Agonists
1987A partial agonist is an agent that requires appreciable receptor occupancy in order to achieve an effect. By way of contrast, full agonists (or strong agonists) have a large spare receptor capacity, that is, these agents produce effects with just a small fraction of their receptors occupied.
