Side interaction

As schematically shown in Fig. 1C, a carrier is an amphiphilic molecule capable of residing at the membrane aqueous interface with its lipophilic side interacting with the lipid of the membrane, with polar moieties directed outward into the aqueous phase, and with the polar moieties of a chemical nature to induce an ion into interaction. In the process of a carrier interacting and complexing with the ion, it... [Pg.205]

Fig. 5.5 A model of conformational autocatalysis for the oligopeptide of Fig.5.4. The lowest-energy a-helical form (two-helix bundle, left-hand side) interacts with the frozen metastable (3 form (four-member (3 barrel, center). After a long Monte Carlo run (symbolized by an arrow), which consists of a million of intermediate conformations of various type, both molecules form a strong complex of two (3 type metastable forms right). During this run the a conformation unfolds and then refolds to the (3 conformation. Thus, the (3 metastable form plays a role of a catalyst in the transformation of the a native structure into the (3 form (autocatalysis)...

A ratio of Cas to the rate of catalytic reaction under steady-state conditions (r) gives a rough estimation for the reaction time scale. For typical heterogeneous catalytic processes applied for the production of bulk chemicals and petrochemicals, this value is estimated to be 10-2—101 s (Fig. 5). The changes of the reaction rate caused by the side processes of catalyst modification can take considerably longer. This is attributed to the higher capacity of substances in the catalyst bulk phase that can be involved in side interactions and to a slow rate of side processes in comparison with the stages of the catalytic cycle. [Pg.492]

The phospholipid component appears to determine the preferred mode of combination of repeating units with one another. Llpld-free particles polymerize to three-dimensional aggregates, which are essentially bulk phases devoid of enzymatic activity. ReIntroduction of phospholipid restricts the repeating units to "side to side" Interactions Involving predominantly hydrophobic protein-to-protein bonds. This type of interaction affords an enzymatically-active membrane continuum. It has been concluded, therefore, that the essentiality of phospholipid for normal enzymatic function in such systems reflects cheir ability to "direct" membrane formation rather than any specific chemical effect exerted directly on the enzyme. ... [Pg.228]

When vapor phase resistance dominates, differences between component efficiencies increase as differences between the binary pair diffusion coefficients increase. If all the vapor diffusion coefficients are equal, indicating minimum liquid-side interaction, all component efficiencies are equal. [Pg.1055]

This rearrangement had the effect of opening up the pore in the middle of the membrane, and making it narrowest at the cytoplasmic membrane surface, where the a-helices now came close enough to associate by side-to-side interactions around the ring. Thus there appear to be two alternative configurations of M2 helices around the pore one (the shut configuration) stabilized by side-to-... [Pg.366]

In the general case an adsorbed molecule X is subjected to interactions on three sides interactions with the surface of the adsorbent or a surface site, interactions with adjacent molecules Y in the adsorbed monolayer (assuming monolayer adsorption), and interactions with adjacent molecules Z in the unadsorbed phase. For gas-solid systems of chromatographic interest, adsorbed sample molecules are widely separated (low... [Pg.235]

The other factors that indirectiy influence yam crimp and o-FVF are nesting, ply waviness, side interaction of yams and yam overlap. If they are not in a model, it may mean that either these pecuharities have not been observed in the materials studied or they have not been taken into account. The overview aims at giving an overall picture rather than demanding all the models to have the same level of geometric refinement. [Pg.30]
