15 صفحه اولAcid-induced gelation of enzymatically modified, preheated whey proteins.
Low-pH whey protein gels are formulated using a sequential protocol of heat treatment, enzyme incubation, and cold-set acidification. The heat-induced disulfide and enzyme-catalyzed epsilon-(gamma-glutamyl)lysine linkages, both at neutral pH, produce a polymerized protein solution. The molecular weights of these samples show an exponential increase with protein concentration. The additional enz...
متن کاملIonomeric Films of Alginic Acid
Transparent, flexible films could be made by casting aqueous solutions of alginic acid, but they dissolved in water. When films were made from a solution of alginic acid and multivalent ions, they were still water soluble. However, when alginic acid films were immersed in a solution of salts with multivalent ions, they dissolved in water much more slowly, if at all. Treatment with calcium and z...
متن کاملSwelling-induced chloride currents in neuroblastoma cells are calcium dependent.
The effects of osmotic stress on chloride (CI-) currents in the human neuroblastoma cell line CHP-100 were evaluated. Following exposure to hypoosmotic solution, an increase in whole-cell CI- current was observed. This current was blocked by the CI- channel blocker 5-nitro-2-(3-phenylpropylamino)-benzoic acid (NPPB). In cells loaded with the CI- permeability marker 125I, exposure to hypoosmotic...
