Contributors in Biochemistry

Biochemistry

Half of a gap junction. Being embedded in the membrane of each of the cells and composed of six molecules of the integral protein connexin, the hemi-channel allows communication between the cytoplasm ...

Co-translational

Biology; Biochemistry

Descriptive of a process that occurs at the same time as protein synthesis; e.g. folding into a native conformation assisted by a molecular chaperone, transport of a secretory protein across the ...

Ninhydrin reaction

Biology; Biochemistry

A colorimetric method for quantification of amino acids; reaction with ninhydrin oxidises and decarboxylates amino acids and generates an intense blue chromophore from reduction and coupling of the ...

Synchronous growth

Biology; Biochemistry

The co-ordinated passage through the cell cycle of a large mass of cells; sometimes achieved by experimental starvation of the cells to bring them all to the start of S phase, then relieving the ...

Axial ratio

Biology; Biochemistry

A measure of the asymmetry of a macromolecule, assumed to be an ellipsoid, given by the ratio of the major axis to the minor axis; it is evaluated from physical properties, e.g. hydrodynamic ...

Cryptochrome

Biology; Biochemistry

A blue light- and ultraviolet-A-sensitive receptor protein, containing pterin and flavin prostehetic groups; found ubiquitously in plants and in mammals, and linked to the circadian response of these ...

Liposome

Biology; Biochemistry

A synthetic micelle formed by dispersion of a polar lipid in aqueous solution in such a way that it forms into lipid-bilayer-encapsulated vesicles; useful for packaging of drugs or enzymes for ...
