Contributors in Biochemistry

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 ...

lipid bilayer (bimolecular sheet)

Biology; Biochemistry

A synthetic or natural membrane in which amphipathic lipids are arranged in two layers with their non-polar chains directed inwards, towards each other, and their polar groups directed outwards, ...

unit membrane Danielli-Davson model

Biology; Biochemistry

A model for the structure of biological membranes; a variation of the Danielli-Davson model in which the membrane is composed of plaques of bilayer (the unit membrane); the outer leaflet turns over ...

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 ...

molten globule intermediate

Biology; Biochemistry

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

kinetic partitioning

Biology; Biochemistry

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

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 ...
