Neighbor effects

The reverse reaction is an intramolecular acidolysis of amide group by the o-carboxyhc acid to reform anhydride and amine. This unique feature is the result of an ortho neighboring effect. In contrast, the acylation of an amine with ben2oic anhydride is an irreversible reaction under the same reaction conditions. The poly(amic acid) stmcture (8) can be considered as a class of polyamides. Aromatic polyamides that lack ortho carboxylic groups are very... 

The aim of the present paper is to apply the impurity KKR Green s function method to the study of nearest-neighbor effective-pair interaction energies (NN-EPIE s) in low-concentrated fee di.sordered alloys (H = host, X = impurity c < 0.1). It is...

The solution found when the rate equations are pul equal to zero corresponds to equilibrium in the case of a uniform reaction environment, but also characterizes the steady state if it is assumed that the linear lattice separates two two-dimensional spaces such that on the one side the reaction is all 0 —> 1 according to ku k2, and k3 and on the other all 1 —> 0 according to k2 k2 and k3. As the k s can include functions of the environment within them such as the concentrations of a transported substance with which the lattice reacts, this model can be used to discuss transport through membranes with reactions governed by near neighbor effects. It will be clear that the reactivity of the linear lattice must be defined in an asymmetric fashion in order to obtain transport. 

Comparing B with the familiar Rouse A matrix of Eq. (11), we see that the bond correlations have produced second-neighbor effects in the chain dynamics.

We applied the hole digging method to several samples of molecular clusters and quantum spin glasses. The most detailed study has been done on the Fe8 system. We found the predicted square-root t relaxation, Eq. (11), in experiments on fully saturated Fe8 crystals [16, 79] and on nonsaturated samples [34]. Figure 22 analyzes the dipolar distributions, revealing a remarkable structure due to next-nearest-neighbor effects [34]. These results are in good agreement with simulations [80, 55]. 

Even in macromolecular systems, the secondary binding forces mentioned up to here act in the same manner as in the case of low molecular weight compounds, if one considers secondary bonds individually. However, for all practical purposes, they act at the same time in an extremely complicated manner, concertedly and never separately. Moreover, each active site of the molecule interacts cooperatively with other sites because of the neighboring effect (for details see Sect. 4). Therefore, in intra- and intermacromolecular interaction systems, it is quite difficult to investigate separately the effective secondary binding forces, and it should be noted that the total interaction force might not be the sum of the individual binding forces. 

Nearest-neighbor effects refer to the reciprocal influence of adjacent amino acids on protein folding. In some cases, this term also refers to amino acids that are close in the 3-D structure of the protein (<8-10 A away), but distant in the sequence. Early studies found a nonrandom assorting of amino acids in secondary structures by pair-wise analysis of protein sequences (43). More recently, it was reported that the preference of pairs of amino acids for secondary structure was determined, in part.
