| van't Hoff, Jacobus | <person> Dutch chemist and Nobel laureate, 1852-1911. See: van't Hoff's equation, van't Hoff's law, van't Hoff's theory, Le Bel-van't Hoff rule. (05 Mar 2000) |

| van't Hoff's equation | Equation for osmotic pressure of dilute solutions. See: van't Hoff's law. For any reaction, d(ln Keq/d(1/T) equals -dH/R where Keq is the equilibrium constant, T the absolute temperature, R is the universal gas constant, and dH is the change in enthalpy; thus, plotting ln Keq vs. 1/T allows the determination of dH.

| van't Hoff's law | In stereochemistry, all optically active substances have one or more multivalent atoms united to four different atoms or radicals so as to form in space an unsymmetrical arrangement, the osmotic pressure exerted by any substance in very dilute solution is the same that it would exert if present as gas in the same volume as that of the solution; or, at constant temperature, the osmotic pressure of dilute solutions is proportional to the concentration (number of molecules) of the dissolved substance; i.e., the osmotic pressure, π, in dilute solutions is π = RTσci, where R is the universal gas constant, T is the absolute temperature, and ci is the molar concentration of solute i, the rate of chemical reactions increases between two-and three-fold for each 10캜 rise in temperature. (05 Mar 2000) |
| van't Hoff's theory | That substances in dilute solution obey the gas laws. Compare: van't Hoff's law. (05 Mar 2000) |
| Le Bel-van't Hoff rule | The number of stereoisomers of an organic compound is 2n where n represents the number of asymmetric carbon atoms (unless there is an internal plane of symmetry). A corollary of their simultaneously announced conclusions, in 1874, that the most probable orientation of the bonds of a carbon atom linked to four groups or atoms is toward the apexes of a tetrahedron, and that this accounted for all then-known phenomena of molecular asymmetry (which involved a carbon atom bearing four different atoms or groups). See: stereoisomerism. (05 Mar 2000) |
| Arrhenius plot | A plot of the logarithm of reaction rate against the reciprocal of absolute temperature. For a single stage reaction this gives a straight line from which the activation energy and the frequency factor can be determined. Often applied to data from complex biological systems when the form observed is frequently a series of linear portions with sudden changes of slope. Great caution must be observed in interpreting such slopes in terms of activation energies for single processes. (18 Nov 1997) |
| Ramachandran plot | A graphical representation in which the dihedral angle of rotation about the alpha-carbon to carbonyl-carbon bond in polypeptides is plotted against the dihedral angle of rotation about the alpha-carbon to nitrogen bond. Synonym: conformational map. (05 Mar 2000) |
| Woolf-Lineweaver-Burk plot | <statistics> A graph made to analyse how fast an enzyme can convert its substrate into its product, depending on how much substrate is present (its concentration) and to determine its maximum speed (after which the enzyme does not get any faster no matter how high the concentration of substrate gets), called Vmax. It is a plot of 1/v versus 1/[S], where v=rate of product formation and [S]=the concentration of the substrate. Synonym: Lineweaver-Burk plot, Woolf-Lineweaver-Burk plot. (05 Mar 2000) |
| plot | 1. A small extent of ground; a plat; as, a garden plot. 2. A plantation laid out. 3. A plan or draught of a field, farm, estate, etc, drawn to a scale. Origin: AS. Plot; cf. Goth. Plats a patch. Cf. Plat a piece of ground. 1. Any scheme, stratagem, secret design, or plan, of a complicated nature, adapted to the accomplishment of some purpose, usually a treacherous and mischievous one; a conspiracy; an intrigue; as, the Rye-house Plot. "I have overheard a plot of death." (Shak) "O, think what anxious moments pass between The birth of plots and their last fatal periods!" (Addison) 2. A share in such a plot or scheme; a participation in any stratagem or conspiracy. "And when Christ saith. Who marries the divorced commits adultery, it is to be understood, if he had any plot in the divorce." (Milton) 3. Contrivance; deep reach thought; ability to plot or intrigue. "A man of much plot." 4. A plan; a purpose. "No other plot in their religion but serve Got and save their souls." 5. In fiction, the story of a play, novel, romance, or poem, comprising a complication of incidents which are gradually unfolded, sometimes by unexpected means. "If the plot or intrigue must be natural, and such as springs from the subject, then the winding up of the plot must be a probable consequence of all that went before." (Pope) Synonym: Intrigue, stratagem, conspiracy, cabal, combination, contrivance. Origin: Abbrev. From complot. Source: Websters Dictionary (01 Mar 1998) |
| control plot | A plot in which no vegetation will be cut and natural succession will occur. A control plot serves as a baseline to compare other treatments (Early, Mid and Late Seral). (05 Dec 1998) |
| Hanes plot | A graphical representation of enzyme kinetic data in which the substrate concentration divided by the velocity (i.e., the [S]/v ratio) is plotted on the vertical axis as a function of [S]. Sometimes referred to as the Hanes-Wilkinson plot. (05 Mar 2000) |
| Scatchard plot | A method for analysing data for freely reversible ligand/receptor binding interactions. The graphical plot is: Bound ligand/Free ligand) against (Bound ligand), the slope gives the negative reciprocal of the binding affinity, the intercept on the x axis the number of receptors (Bound/Free becomes zero at infinite ligand concentration). The Scatchard plot is preferable to the Eadie Hoffstee plot for binding data because it is more dependent upon the values at high ligand concentration which will be the most reliable values. A nonlinear Scatchard plot is often taken to indicate heterogeneity of receptors, although this is not the only explanation possible. (18 Nov 1997) |
| hill plot | A method which is used to find out how many binding sites of a particular type are present on a given protein molecule. The Hill plot does this by graphical representation of the molecule. (09 Oct 1997) |
| hydropathy plot | <chemistry, investigation> A graph which shows how hydrophobic each amino acid in a polypeptide is versus where it is located on the polypeptide. The hydropathy plot is used to find clusters of hydrophobic amino acids, which could indicate that the polypeptide in question is a transmembrane protein. A transmembrane protein has hydrophilic parts which protrude out on either side of the cellular membrane, and a hydrophobic centre which lies within the membrane. (09 Oct 1997) |
| double-reciprocal plot | <statistics> A graph made to analyse how fast an enzyme can convert its substrate into its product, depending on how much substrate is present (its concentration) and to determine its maximum speed (after which the enzyme does not get any faster no matter how high the concentration of substrate gets), called Vmax. It is a plot of 1/v versus 1/[S], where v=rate of product formation and [S]=the concentration of the substrate. Synonym: Lineweaver-Burk plot, Woolf-Lineweaver-Burk plot. (05 Mar 2000) |
