|---|---|
| hydrophilic group | <chemistry> A polar group or one that can take part in hydrogen bond formation, for example OH, COOH, NH2. Confers water solubility or in lipids and macromolecules causes part of the structure to make close contact with the aqueous phase. (18 Nov 1997) |
| hydroxyl group | An -OH or alcohol group on a larger molecule. The oxygen is single-bonded to the hydrogen and has one free bond to the rest of the molecule. Molecules with one or more hydroxyl groups are called alcohols. (09 Oct 1997) |
| simbu group viruses | A group of viruses in the bunyavirus genus of the bunyaviridae family that are found in asia, africa, and the americas. (12 Dec 1998) |
| sodium group | The alkali metals: cesium, lithium, potassium, rubidium, and sodium. (05 Mar 2000) |
| species group | <zoology> The taxonomic categories species and subspecies. (09 Jan 1998) |
| nitrogen group | Five trivalent or quinquivalent elements whose hydrogen compounds are basic and whose oxyacids vary from monobasic to tetrabasic: nitrogen, phosphorus, arsenic, antimony, and bismuth. (05 Mar 2000) |
| nitrogenous group transferases | <enzyme> Enzymes that catalyze the transfer of nitrogenous groups, primarily amino groups, from a donor, generally an amino acid, to an acceptor, usually a 2-oxoacid. Registry number: EC 2.6 (12 Dec 1998) |
| nocardioform group | A group of actinomycetes that forms mycelia that break up into rod-shaped or coccoid elements. Certain genera in this group are pathogenic to man. (12 Dec 1998) |
| subscapular group of axillary lymph nodes | Node's of the axillary region located along the subscapular vein and its tributaries; they receive afferent vessels from the dorsal surface of the thorax and scapular region, and send efferent vessels to the central group of lymph nodes. Synonym: nodi lymphatici axillares subscapulares, posterior group of axillary lymph nodes. (05 Mar 2000) |
| nonpolar group | <chemistry> Group in which the electronic charge density is essentially uniform and that cannot therefore interact with other groups by forming hydrogen bonds or by strong dipole dipole interactions. In an aqueous environment, nonpolar groups tend to cluster together, providing a major force for the folding of macromolecules and formation of membranes. Clusters are formed chiefly because they cause a smaller increase in water structure (decrease in entropy) than dispersed groups. Nonpolar groups interact with each other only by the relatively weak London van der Waals forces. (12 Mar 1998) |
| dakota group | <geology> A subdivision at the base of the cretaceous formation in Western North America; so named from the region where the strata were first studied. Source: Websters Dictionary (01 Mar 1998) |
| sulfur group | The elements sulfur, selenium, and tellurium; they form dibasic acids with hydrogen, and their oxyacids are also dibasic. (05 Mar 2000) |
| sulfur group transferases | <enzyme> Enzymes that catalyze the transfer of sulfur atoms (2.8.1), sulfur groups (2.8.2) or coenzyme a (2.8.3). Registry number: EC 2.8 (12 Dec 1998) |
| symptom group | See: syndrome, complex. (05 Mar 2000) |
