| carbonyl group | A group in which an oxygen atom is double-bonded to a carbon atom: O=C. The carbon atom then has two additional bonds to attach to the rest of the molecule. Organic molecules containing a carbonyl group are a very important, major group of compounds studied in the field of organic chemistry. (09 Oct 1997) |
|---|---|
| carboxyl group | -COOH group. One of the oxygens is double-bonded to the carbon atom, making it a carbonyl group, and the other oxygen is single bonded to the carbon on one side, and single bonded to the hydrogen on the other. The remaining bond on the carbon atom is attached to the rest of the molecule. Organic molecules containing carboxyl groups are an important, major group of compounds studied in the field of organic chemistry. (09 Oct 1997) |
| vanadium group | Those elements resembling vanadium in chemical and metallurgical properties; included with vanadium are niobium and tantalum. (05 Mar 2000) |
| marathon group psychotherapy | A type of group psychotherapy characterised by uninterrupted sessions for periods of hours or days, with minimal interruptions for food and rest. (05 Mar 2000) |
| genus-group | <zoology> The taxonomic categories genus and subgenus. (09 Jan 1998) |
| pectoral group of axillary lymph nodes | Lymph nodes located along the lateral thoracic vein; they receive the drainage of the pectoral region, including most of the drainage of the breast. Synonym: nodi lymphatici axillaris pectorales, anterior group of axillary lymph nodes. (05 Mar 2000) |
| central group of axillary lymph nodes | Nodes located around the midportion of the axillary vein; they receive afferent vessels from the lateral (brachial), pectoral, and subscapular groups of axillary nodes and send efferent vessels to the apical group of axillary node's. (05 Mar 2000) |
| peer group | Group composed of associates of same species, approximately the same age, and usually of similar rank or social status. (12 Dec 1998) |
| glycosyl group | <biochemistry> A radical chemical group on a larger molecule, derived from a sugar or starch molecule, which is attached to the rest of the larger molecule by way of a glycosidic bond. (09 Oct 1997) |
| C group viruses | A serologic group of the genus Bunyavirus (formerly called group C arboviruses), composed of 12 species including Caraparu, Murutucu, and Oriboca virus. (05 Mar 2000) |
| characterizing group | A group of atoms in a molecule that distinguishes the class of substances in which it occurs from all other classes; thus carbonyl (CO) is the characterizing group of ketones; COOH, of organic acids, etc. (05 Mar 2000) |
| r group | <chemistry> A chemical abbreviation that normally denotes an alkyl group, but is occasionally used to refer to other organic groups. (09 Oct 1997) |
| chlorine group | The halogens. (05 Mar 2000) |
| group | 1. A cluster, crowd, or throng; an assemblage, either of persons or things, collected without any regular form or arrangement; as, a group of men or of trees; a group of isles. 2. An assemblage of objects in a certain order or relation, or having some resemblance or common characteristic; as, groups of strata. 3. <biology> A variously limited assemblage of animals or planta, having some resemblance, or common characteristics in form or structure. The term has different uses, and may be made to include certain species of a genus, or a whole genus, or certain genera, or even several orders. 4. A number of eighth, sixteenth, etc, notes joined at the stems; sometimes rather indefinitely applied to any ornament made up of a few short notes. Origin: F groupe, It. Gruppo, groppo, cluster, bunch, packet, group; of G. Origin: cf. G. Krepf craw, crop, tumour, bunch. See Crop. Source: Websters Dictionary (01 Mar 1998) |
| group agglutination | Agglutination by antibodies specific for minor (group) antigens common to several microorganisms, each of which possesses its own major specific antigen. Synonym: cross agglutination. (05 Mar 2000) |
