Molecular biology

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.

Autoimmune disease

Biology; Biochemistry

A failure of tolerance; the reaction of an individual's immune system towards some of the individual's own proteins as if they were foreign proteins, e.g. myasthenia gravis, rheumatoid arthritis.

Erybraedin C

Biology; Biochemistry

A pterocarpan purified from the plant Bituminaria bituminosa that inhibits both the cleavage and religation activities of human topoisomerase I and has been shown to have an anti-tumor activity.

Pleiotropism

Biology; Biochemistry

A characteristic of action of some hormones; expression of several activities, e.g. the action of insulin both to promote glucose uptake by skeletal muscle cells and to promote protein synthesis.
