| Lineweaver Burke plot | A plot of 1/v against 1/S for an enzyme catalysed reaction, where v is the initial rate and s the substrate concentration. From the equation: 1/v = 1/Vmax(1+Km/S) the parameters Vmax and Km can be determined. The equation overweights the contribution of the least accurate points and other methods of analysis are preferred. See: Eadie Hofstee plot. (18 Nov 1997) |

| Lineweaver-Burk equation | A rearrangement of the Michaelis-Menten equation, 1/v = 1/Vmax + (Km/Vmax)(1/[S]). Compare: double-reciprocal plot. (05 Mar 2000) |
| 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) |

a rearrangement of the Michaelis-Menten equation of enzyme kinetics to give 1v = KMVmax[S] + 1Vmax , where v is the reaction velocity, [S] is the substrate concentration, Vmax is the maximum velocity, and KM is the Michaelis constant. If an enzyme reaction follows Michaelis-Menten kinetics, then a plot of 1/v against 1/[S] results in a straight line with defined slope and intercepts; see Lineweaver-Burk plot, under plot.

| Lineweaver-Burk p. |
the double reciprocal plot of an enzyme-catalyzed reaction, obtained from the Lineweaver-Burk equation by graphing 1/v as a function of 1/[S]. If the reaction obeys Michaelis-Menten kinetics a straight line is obtained with x-intercept of -1/KM, y-intercept of 1/Vmax, and slope of KM/Vmax. Although unreliable for large values of 1/v, the plot is widely used. It is also sometimes used in the classification of enzyme inhibitors, which all cause distinctive alterations in the graph.
