Molecular biology

framework model

Biology; Biochemistry

A proposed sequence of protein folding events in which the random coil, or denatured form, passes through three stages: the formation of fluctuating embyros, in which disconnected regions of ...

An explanation for oxidative phosphorylation that proposes that electron transport builds up a store of energy in the distorted shape of the mitochondrial inner membrane, the relaxation of which is ...

chemiosmotic theory

Biology; Biochemistry

A proposed mechanism of oxidative phosphorylation in the mitochondrion and chloroplast that requires (1) electron transport to be arranged across the mitochondrial or chloroplast membrane so that ...

chemical coupling hypothesis

Biology; Biochemistry

Explanation for oxidative phosphorylation by analogy with substrate-level phosphorylation, i.e. when a phosphate derivative of an electron carrier is oxidized, it becomes a high-energy phosphate ...

R

Biology; Biochemistry

A designation of absolute configuration at an asymmetrical center; classified as R (rectus) or S (sinister) according to the arrangement in space of its substituents, which are assigned precedence ...

prochirality

Biology; Biochemistry

The symmetry characteristic of a molecule, or of a center within a molecule, by which like groups may be distinguished, e.g. the property of citric acid that allows aconitase to distinguish between ...

symmetry

Biology; Biochemistry

One of the geometrical properties of a chemical or any other structure. Reflectional symmetry is the property of a molecule or object that permits it to be superimposed on its mirror image; ...
