Bridging Effect Divalent Salt

We now consider the bridging configuration of nonbonded monovalent monomers mediated by divalent counterions. Let us assume that some of the adsorbed divalent ions participate in bridging. When bridging is included, the niitiitriization of the free [Pg.295]

We must add the third virial term in the chain free energy (E5, Eq. (6.37)) to maintain stability in the system in the case of a negative u/. Combining Eqs. (6.45) and (6.46), therefore, the chain free energy takes the form. [Pg.296]

The other parts of the free energy depend only on the numbers and valencies of different species of free ions and therefore remain unaltered. They are given as F2 in Eq. (6.25) and F3 in Eq. (6.30). In all these cases, 02 = a2a + 2b. [Pg.297]

In conclusion, our model predicts a coil-globule transition, mediated by bridging due to divalent ions, which depends sensitively on temperature and the dielectric heterogeneity, as well as on the availability of divalent counterions. [Pg.299]

Since heat (as well as HP) causes a denaturation of the cell membranes and also liberates the PME, the divalent cations (Ca, Mg) from the cell liquor come into contact with the deesterified pectin and form Ca-bridges. Within canning, this tissue firming effect is further promoted via the addition of Ca-salts. [Pg.275]
