Biophysical chemistry is a physical science that uses the concepts of physics and physical chemistry for the study of biological systems. [1] The most common feature of the research in this subject is to seek an explanation of the various phenomena in biological systems in terms of either the molecules that make up the system or the supra-molecular structure of these systems. [2]
Biophysical research shares significant overlap with biochemistry, molecular biology, physical chemistry, physiology, nanotechnology, bioengineering, computational biology, biomechanics, developmental biology and systems biology. The term biophysics was originally introduced by Karl Pearson in 1892.
Circular Dichroism – method to measure chirality of a sample using circularly polarized light. This technique is commonly used to determine protein structure. Computational chemistry – use of numerical methods to probe the structure and dynamical equilibrium in biological systems. Cryobiology – studies the effects of low temperatures on ...
Physical biochemistry is a branch of biochemistry that deals with the theory, techniques, and methodology used to study the physical chemistry of biomolecules. [1] It also deals with the mathematical approaches for the analysis of biochemical reaction and the modelling of biological systems. It provides insight into the structure of ...
The Journal of Proteomics is a peer-reviewed scientific journal published by Elsevier. It is the official journal of the European Proteomics Association and the editor-in-chief is Juan Calvete. [1] It was established in 1979 as the Journal of Biochemical and Biophysical Methods, [2] obtaining its current name in 2008. [3]
In these methods, a reacting system initially at equilibrium is perturbed rapidly and then observed as it relaxes back to equilibrium. [ 1 ] [ 2 ] [ 3 ] In the case of temperature jump, the perturbation involves rapid heating which changes the value of the equilibrium constant , followed by relaxation to equilibrium at the new temperature.
Sometimes a hybrid method is employed such that the binding is done by the batch method, but the solid phase with the target molecule bound is packed onto a column and washing and elution are done on the column. The ligands used in affinity chromatography are obtained from both organic and inorganic sources.
According to some opinions, [6] [7] living eukaryotic cells perform isoelectric focusing of proteins in their interior to overcome a limitation of the rate of metabolic reaction by diffusion of enzymes and their reactants, and to regulate the rate of particular biochemical processes. By concentrating the enzymes of particular metabolic pathways ...
