Molecular biology

A compound with more than one amino group that often contains short chains of carbon atoms separated by a nitrogen atom and forms a secondary amine; associated in the cell with nucleic acids; e.g. ...

molecular organelle

Biology; Biochemistry

A very large, non-membrane-limited aggregate of subunits that in prokaryotes functions like an organelle. They occur also in eukaryotes, e.g. the proteasome, which as a 26 S multimer is a cylinder 40 ...

colloid

Biology; Biochemistry

A dispersion of a high-molecular-mass solute in a liquid phase. Typically, the colloidal solute is unable to traverse a semi-permeable membrane. The solute particles are usually of sufficient size to ...

rescue

Biology; Biochemistry

A strategy in chemotherapy in which lethal doses of an antifolate are given to block nucleotide biosynthesis in rapidly proliferating cells, followed by treatment with 5-formyltetrahydrofolate or ...

ferric chloride test

Biology; Biochemistry

The chelation of Fe 3+ by an a-oxo acid to give a colored product, as a test for metabolic products of amino acids, e.g. with α-oxophenylpyruvate as an indirect test for excess levels of ...

reporter group

Biology; Biochemistry

A chromophore or fluorophore that is sensitive to its environment; a group added to a protein to indicate changes in its environment as the protein is manipulated, e.g. by denaturation or association ...

glycolipid

Biology; Biochemistry

A compound with both lipid and sugar moieties, e.g. lipopolysaccharide of Gram-negative bacteria cell walls, blood group antigens, gangliosides (carbohydrate moieties attached to N-fatty ...
