| structural | <anatomy> Pertaining to or affecting the structure. (18 Nov 1997) |
|---|---|
| structural biology | <study> The study of the three dimensional structures of biological molecules (such as proteins) and their mutual interactions as a means of understanding the functions of these molecules within the cell. (09 Oct 1997) |
| structural colour | A colour created by an optical effect (e.g., via interference, refraction, or diffraction). Many naturally occurring blues fall in this class. Compare: natural pigment. Synonym: schemochromes. (05 Mar 2000) |
| structural formula | A formula in which the connections of the atoms and groups of atoms, as well as their kind and number, are indicated. Synonym: constitutional formula, graphic formula. (05 Mar 2000) |
| structural gene | A gene that codes for a product (e.g. An enzyme, structural protein, tRNA), as opposed to a gene that serves a regulatory role. (18 Nov 1997) |
| structural interface | In dentistry, a boundary between tooth and restorative material. (05 Mar 2000) |
| structural isomerism | Isomerism involving the same atoms in different arrangements; e.g., butyric acids, leucine and isoleucine, glucose and fructose. (05 Mar 2000) |
| structural isomers | <chemistry> Are organic compounds that have the same som formula, meaning the same number of carbons, hydrogens or other type ot atoms. They differ from each other in the way the atoms are connected. Examples are n-butane and 2-methylpropane or ethanol and dimethylether. (09 Jan 1998) |
| structuralism | A branch of psychology interested in the basic structure and elements of consciousness. (05 Mar 2000) |
| structure | <microscopy> The mode of construction of an animate or inanimate body or system from units such as atoms, ions, molecules, cells, crystals in a fluid, plastic, or solid state. Cf. Morphology. (05 Aug 1998) |
| structure activity analysis | Study in which systematic variation in the structure of a compound is correlated with its activity, in an attempt to determine the characteristics of the (receptor) site at which it acts. (18 Nov 1997) |
| structure proteins | Proteins whose role is for structure and support in tissue and within the cell; e.g., the collagens. (05 Mar 2000) |
| structure-activity relationship | The relationship between the chemical structure of a compound and its biological or pharmacological activity. Compounds are often classed together because they have structural characteristics in common including shape, size, stereochemical arrangement, and distribution of functional groups. Other factors contributing to structure-activity relationship include chemical reactivity, electronic effects, resonance, and inductive effects. (12 Dec 1998) |
| structure-functionalism | The scientific tradition that stresses the relationship between aphysical structure and its function, for example: the related disciplinesof anatomy and physiology. (09 Oct 1997) |
| structured | <biology> Having a definite organic structure; showing differentiation of parts. "The passage from a structureless state to a structured state is itself a vital process." (H. Spencer) Source: Websters Dictionary (01 Mar 1998) |
