Molecular biology

Secondary metabolism

Biology; Biochemistry

Those metabolic pathways, other than those for energy production and for biosynthesis of nucleic acids, proteins, structural components, etc., that are unique to an organism; especially those ...

Expressed sequence tag (EST)

Biology; Biochemistry

A partial coding sequence isolated at random from a cDNA library; like a sequence-tagged site for mapping genomic DNA, used as a landmark for identification and mapping of coding sequences, for ...

Wood-Werkman reaction

Biology; Biochemistry

The proposed reaction, derived from the observed incorporation of isotopic CO 2 into succinate, by which CO 2 condenses with the 3-carbon compound pyruvate to form a 4-carbon compound, ...

Humanised antibody

Biology; Biochemistry

A chimaeric immunoglobulin of human and non-human origin. In order to minimise the possibility of the chimaera being antigenic in humans, only the hypervariable regions of a non-human monoclonal ...

Cis

Biology; Biochemistry

In stereochemistry, descriptive of a substituent on the same side of a structure that prevents equalisation of positions by restricted rotation, e.g. an olefinic bond, a ring or a peptide bond; ...

Nuclear magnetic resonance (NMR)

Biology; Biochemistry

A technique for studying the microenvironment of certain atoms that can absorb energy in a magnetic field, e.g. 1 H, 13 C, 15 N, 31 P. NMR can be used to study the conformation in solution of ...

Enzyme-linked immunosorbent assay (ELISA)

A technique that combines the specificity of an immunoglobulin with the detectability of an enzyme-generated chromophoric product to quantify a macromolecule. The enzyme is covalently attached to the ...
