Molecular biology

The change in optical rotation that accompanies the approach to equilibrium of the two anomers of a sugar from a solution of one anomer alone; also the conversion of one anomer of a sugar into the ...

microtubule

Biology; Biochemistry

A large (30nm diameter) rigid component of the cytoskeleton that is built of α- and β-tubulin subunits and associated proteins and serves as a component of cilia, eukaryotic flagella and mitotic ...

permeability coefficient

Biology; Biochemistry

A quantitative measure of the rate at which a molecule can cross a membrane such as a lipid bilayer; expressed in units of cm/s and equal to the diffusion coefficient divided by the width of the ...

peptidomimetic

Biology; Biochemistry

A small non-peptide molecule, often cyclic, with features of a natural, biologically active peptide, which confer upon it the natural peptide's activity, but which is more stable or easier to ...

half-of-the-sites activity

Biology; Biochemistry

An extreme form of negative co-operativity shown by a multisubunit enzyme in which, as a substrate binds to the active site of one subunit, the affinity for the substrate of an adjacent subunit ...

tetra-antennary

Biology; Biochemistry

Descriptive of a complex-type carbohydrate that has four unbranched oligosaccharide chains at a non-reducing end, often terminated by a sialic acid. Variants are tri-antennary and bi-antennary ...

housekeeping

Biology; Biochemistry

Descriptive of a gene or enzyme that serves an essential function common to all or most cells, e.g. production of energy; as distinguished from specialized functions, such as differentiation or ...
