diffusion coefficient

Biology; Biochemistry

A measure of a molecule's ability to travel through a solution, propelled by Brownian movement; expressed as RT/Nf (cm 2 ·s -1 ), where R is the gas constant, T is the absolute temperature, N is ...

An optical instrument for detection of binding partners. A reflective surface is coated with a one of the pair, and is then exposed to a test solution. If binding occurs, the refractive index of the ...

hierarchical condensation

Biology; Biochemistry

The hypothesis that, during the folding of a protein in solution, some regions are much more likely to adopt a secondary structure and that, once formed, these interact to direct the subsequent ...

intermediary metabolism

Biology; Biochemistry

The individual enzymic reactions that in a tissue or inside a cell transform one metabolite into another, e.g. the conversion of lactate into glucose by the liver, the conversion of leucine into ...

ATPase

Biology; Biochemistry

An enzyme that hydrolyses ATP; usually the partial activity of an enzyme, or system of enzymes, that uses the energy made available by the hydrolysis of ATP to drive an energetically unfavorable ...

genotype

Biology; Biochemistry

The genetic composition of a cell or organism, usually with reference to a particular set of alleles that may be homozygous or heterozygous for a trait; the phenotype is the appearance of the cell or ...

immunoaffinity chromatography

Biology; Biochemistry

A variant of affinity chromatography in which an antibody coupled to the stationary phase adsorbs an antigen which is subsequently eluted at a different pH or a higher salt concentration. Specific ...
