Biochemistry

Stokes radius

Biology; Biochemistry

On the assumption that it is a sphere, the apparent radius of a macromolecule in solution, as determined from its hydrodynamic behavior, i.e. intrinsic viscosity, diffusion or sedimentation ...

Blunt ended

Biology; Biochemistry

Descriptive of the structure of double-stranded DNA in which neither strand of the duplex extends further from the end than the other; often the product of cleavage by a restriction endonuclease.

Flush ended

Biology; Biochemistry

Descriptive of the structure of double-stranded DNA in which neither strand of the duplex extends further from the end than the other; often the product of cleavage by a restriction endonuclease.

A derivative of perhydrocyclopentanophenanthrene; a more oxygenated product of cholesterol, with the C-17 side chain shortened or removed. Many steroids are hormones, e.g. cortisone, progesterone, ...

Advanced glycation end product (AGE)

Biology; Biochemistry

The degradation product of a protein-carbohydrate addition product such as haemoglobin A 1C , the Schiff base formed by the condensation of an ε-amino group of haemoglobin with glucose.

Flip-flop circuit

Biology; Biochemistry

The sequence of enzymic events that permits the periodic expression of either of two genes, but never both together, e.g. control of the expression of two of the flagellar proteins of Salmonella.

Linkage map

Biology; Biochemistry

A description of a genome derived from the screening of many phenotypes to determine the frequency with which genes occur together, and can then be placed in appropriate proximity to one another.
