| hydrophobic | <chemistry> Not readily absorbing water or being adversely affected by water, as a hydrophobic colloid. (18 Nov 1997) |
|---|---|
| hydrophobic bond | See: hydrophobic interaction. (05 Mar 2000) |
| hydrophobic bonding | <chemistry> Interaction driven by the exclusion of nonpolar residues from water. It is an important determinant of protein conformation and of lipid structures and is considered to be a consequence of maximising polar interactions rather than a positive interaction between apolar residues. (18 Nov 1997) |
| hydrophobic colloid | A colloidal solution in which the disperse particles are solid and lyophobe or hydrophobe, and are therefore sharply demarcated from the fluid in which they are suspended. Synonym: hydrophobic colloid, lyophobic colloid, suspension colloid. Origin: suspension + G. Eidos, resemblance (05 Mar 2000) |
| hydrophobic effect | <chemistry> The tendency for the nonpolar portions of a group of lipid molecules to clump together with one another and exclude water and other polar molecules. The polar portions of the lipid molecules end up facing out. The hydrophobic effect is primarily responsible for the construction of lipid bilayers. (09 Oct 1997) |
| hydrophobic interaction | <chemistry> The attractive force between molecules due to the close positioning of non-hydrophilic portions of the two molecules. (09 Oct 1997) |
| hydrophobic tetanus | A type of local tetanus that follows wounds to the face and head; after a brief incubation (1-2 days) the facial and ocular muscles become paretic yet undergo repeated tetanic spasms. The throat and tongue muscles may also be affected. Synonym: cerebral tetanus, head tetanus, hydrophobic tetanus, rose cephalic tetanus, Rose's cephalic tetanus. (05 Mar 2000) |
| absorption chromatography | <investigation> Techniques for separating molecules based on differential absorption and elution. Term for separation methods involving flow of a fluid carrier over a nonmobile absorbing phase. (18 Nov 1997) |
| adsorption chromatography | Chromatography in which separation of substances is achieved by the difference in degree of adsorption of the compounds to a stationary phase. (05 Mar 2000) |
| affinity chromatography | <investigation> A technique of analytical chemistry used to separate and purify a biological molecule from a mixture, based on the attraction of the molecule of interest to a particular ligand which has been previously attached to a solid, inert substance. The mixture is passed through a column containing the ligand attached to the stationary substance, so that the molecule of interest stays within the column while the rest of the mixture continues through to the end. Then, a different chemical is flushed through the column to detach the molecule from the ligand and bring it out separately from the rest of the mixture. (09 Feb 1998) |
| gas chromatography | <technique> A chromatographic technique (a type of column chromatography) in which the stationary phase is solid while the mobile phase is gaseous samples. The gaseous samples are separated based on their different adsorption ability to the solid phase. (09 Oct 1997) |
| gas-liquid chromatography | <technique> A chemistry lab technique, a type of column chromatography, used to separate the components of a mixed substance. The substance is held stationary by an inert solid coated with an inert liquid which is not likely to evaporate (i.e. Is nonvolatile), while a gas (called an eluant) flows past it bringing out the components one at a time. (09 Oct 1997) |
| paper chromatography | <technique> Separation method in which filter paper is used as the support. A type of chromatography in which the stationary phase is a sheet of special-grade filter paper. It is in all other aspects similar to thin-layer chromatography. Not a very sensitive method, but historically important as one of the first methods available for separating natural compounds. (07 Mar 2000) |
| gel exclusion chromatography | <investigation> A lab technique, a type of column chromatography, used to separate the components of a mixture by molecular size and to collect the molecules which are larger than a certain size. It is similar to gel filtration, small molecules are slowed or trapped by the pores in the gel beads filling the column, while large molecules, too large to fit into the pores, slide past the beads and get to the bottom of the column first. at this point, the large molecules are collected. Gel exclusion refers to the maximum size of molecule which will fit into the gel bead pores, and this lab technique is used to collect the molecules in the mixture which are larger than, or excluded from, the pores.
