Non-covalent interactions in biomacromolecules

Physical Chemistry Chemical Physics, 2007
Non-covalent interactions play an important role in chemistry, physics and especially in biodisciplines. They determine the structure of biomacromolecules such as DNA and proteins and are responsible for the molecular recognition process. Theoretical evaluation of interaction energies is difficult; however, perturbation as well as variation ...

Covalent interactions in oxides

Journal of Electron Spectroscopy and Related Phenomena, 2014
Abstract The covalent character of ionic metal compounds, in particular oxides, may lead to substantial departures from nominal oxidation states. Since this covalent character changes the effective charge of the cation, it contributes to the chemical and physical properties of these compounds.

Studying non-covalent drug–DNA interactions

Archives of Biochemistry and Biophysics, 2015
Drug-DNA interactions have been extensively studied in the recent past. Various techniques have been employed to decipher these interactions. DNA is a major target for a wide range of drugs that may specifically or non-specifically interact with DNA and affect its functions.

Covalent Interaction

2012
Reviewed in historical context, bond order emerges as a vaguely defined concept without a clear theoretical basis. As an alternative, the spherical standingwave model of the extranuclear electronic distribution on an atom provides a simple explanation of covalent bond order as arising from the constructive and destructive interference of wave patterns.

Ionic-covalent collision interactions

International Journal of Quantum Chemistry, 2009
Several classes of collision problems are mediated by interactions between ionic and covalent potential energy curves. Two prominent cases are ion-ion recombination, A+ + B− A + B, and electron capture in multiply charged ion, atom collisions, Aq+ + B A(q – 1)+ + B+.

Non‐Covalent Interactions in Polysaccharide Systems

Macromolecular Bioscience, 2006
AbstractSummary:This paper describes the behavior of some polysaccharides with well‐known chemical structures and in which the influence of cooperative secondary interactions play an important role. The roles played by hydrophobic and ionic interactions (including ionic selectivity) on polysaccharide conformation and gelation are discussed ...

Identifying Strong Covalent Interactions with Pauli Energy

The Journal of Physical Chemistry A, 2018
As one of the most widely used chemical concepts whose origin can be traced back to Lewis theory of bonding a century ago, a covalent bond involves sharing one or more pairs of electrons between atoms. A strong covalent interaction (SCI) is such a covalent bond that two or more electron pairs are shared, yielding a double, triple, quadruple, or even ...

Genotoxicity of non-covalent interactions: DNA intercalators

Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 2007
This review provides an update on the mutagenicity of intercalating chemicals, as carried out over the last 17 years. The most extensively studied DNA intercalating agents are acridine and its derivatives, that bind reversibly but non-covalently to DNA. These are frameshift mutagens, especially in bacteria and bacteriophage, but do not otherwise show a
