✦ Synopsis

Complexing tendencies of N,N-dimethylbenzamide and N,N-dimethylanisamide toward theophylline and riboflavin in water were found to be significantly less than those of N-substituted and N-monomethyl analogs. It is suggested that rotation of N,N-dimethylamide group about the benzene ring-carbonyl carbon bond may inhibit formation of such complexes. N,N-Dimethylcinnamamide whose N,N-dimethylamide group can lie o n the same plane as the styrene group was shown to be as good an interactant as the unsubstituted cinnamamide.

We report on the effects that the presence of ethylene glycol or glycerol has on the oxygen affinity of hemoglobin. We attribute these effects to an altered equilibrium between T and R quaternary conformations of hernoglobin and separate them into hulk-electrostatic and non-bulk-electrostatic contri

BACKGROUND: Protein conformational modifications and water-protein interactions are two major factors believed to induce instability of protein and eventually affect the solubility of milk protein concentrate (MPC) powder. To test these hypotheses, MPC was stored at different water activities (a w 0

In advanced cirrhosis there is a reduction in the brain concentration of many organic osmolytes, particularly myo-inositol (MI). Hyponatremia could theoretically aggravate these changes as a result of hypo-osmolality of the extracellular fluid. The aim of this study was to determine the effects of h
