Biochemistry

The scientific study of the chemistry of living matter.

Contributors in Biochemistry

Biochemistry

The transport of compounds across a membrane that is unmediated by any mechanism and is independent of energy sources, and therefore occurs at a rate that is determined by the area of the membrane, ...

Mass spectrometry

Biology; Biochemistry

A technique for separation of a stream of large ions accelerated in a magnetic field. The resistance to deflection of the ion from its path is a measure of the momentum of the ion, and hence of its ...

Kinetic partitioning

Biology; Biochemistry

The hypothesis that in folding of a newly synthesised or renaturing biopolymer, a protein or RNA quickly collapses into condensed structures characterised by a high degree of secondary structure. One ...

Difference Patterson map

Biology; Biochemistry

An interim stage in the solution of a molecular structure from X-ray crystallographic data. Using only the intensities due to heavy atom reflections obtained by subtraction of the reflections of the ...

Comparative anchor tagged site (CATS)

Biology; Biochemistry

An extended DNA sequence that is sufficiently conserved across a spectrum of species, e.g. all mammals or mouse and human, so as to serve as a marker for comparative genome mapping and assist the ...

Molten globule intermediate

Biology; Biochemistry

A stable intermediate between the denatured and native states of a protein which is characterised by a high content of secondary structure but poorly defined tertiary structure, hydrophobic residues ...

Kinetic proofreading

Biology; Biochemistry

A mechanism for assuring fidelity in directed macromolecular synthesis; e.g. in protein synthesis a well matched anti-codon-codon pair, as opposed to a poorly matched pair, will remain associated ...
