Molecular biology

An arrangement in space of the carbon-carbon bonds of the alkyl chains of a fatty acid residue of a membrane lipid. The backbone of the chain is rotated 120Â° from the trans conformation, to force ...

Allostasis

Biology; Biochemistry

The altered state caused by stress, trauma, disease, aging, etc. The cumulative burden (stated in physiological, endocrinological or psychiatric terms, depending upon the context) of the shift from ...

Amniocentesis

Biology; Biochemistry

A procedure to obtain foetal cells during pregnancy by puncturing the womb with a needle and removing some fluid that surrounds the fetus. The procedure is used, in part, to obtain foetal cells from ...

Isotherm

Biology; Biochemistry

A binding curve; at constant temperature, the concentration-dependence of the binding of one material to another, e.g. a gas at various pressures to a solid surface, an amino acid at various ...

Retrograde

Biology; Biochemistry

Having a direction opposed to the normal or usual, e.g. transport from a synapse to the cell body of a neuron or from the distal to the proximal cisternae of the Golgi apparatus; as distinguished ...

Psi (Ψ)

Biology; Biochemistry

A symbol that in a designation of an amino acid sequence denotes a structure that substitutes for a peptide bond, e.g. Gly-Ψ(CH 2 -CO)-Gly is H 2 N-CH 2 -CH 2 -CO-CH 2 -COOH.

Diffusion coefficient

Biology; Biochemistry

A measure of a molecule's ability to travel through a solution, propelled by Brownian movement; expressed as RT/Nf (cm 2 ·s -1 ), where R is the gas constant, T is the absolute temperature, N is ...
