Biochemistry

A linearized display of kinetic data showing dependence of enzyme activity on substrate concentration, i.e. reciprocal of rate against reciprocal of substrate concentration, therefore also termed a ...

Glycolysis

Biology; Biochemistry

One of the central pathways of metabolism in most eukaryotes and many other cells; the sequence of enzymic reactions that converts glucose into lactic acid (anaerobic glycolysis) or into pyruvate ...

Kinetic assay

Biology; Biochemistry

An enzyme-based assay that measures the amount of substrate present by correlation of the rate of reaction with the known dependence of the rate on substrate concentration, usually under first-order ...

Linkage disequilibrium

Biology; Biochemistry

In genetics, the more-frequent-than-random occurrence together of two genetic loci within an individual. This may be due to their proximity on the same chromosome, to selective pressure on their ...

Time-of-flight mass spectrometry (TOF-MS)

Biology; Biochemistry

A variant of MS in which the mass of a molecular ion is calculated from the time of travel from the point of ionisation to the detector. TOF-MS uses a pulsed ionising source such as a laser or 252 ...

Fourier transform-mass spectrometry (FT-MS)

Biology; Biochemistry

A variant of mass spectrometry in which a molecular ion is stabilised in a cyclotron orbit and detected by the frequency of its oscillation. The consequent long half-life and non-destructive ...

Human leucocyte antigen (HLA)

Biology; Biochemistry

An antigen on the surface of human cells that consists of a generally invariant β 2 -microglobulin and a larger polypeptide chain that is characteristic of the individual; responsible for most cases ...
