NettetLineweaver-Burk 双倒数作图 酶促反应中的米氏常数的测定和Vmax的测定有多种方法。 比如固定反应中的酶浓度，然后测试几种不同底物浓度下的起始速度，即可获得Km … NettetSubstrate-Velocity Curves and Lineweaver-Burk Plots 1 In this example, we’ll make a combination graph commonly used to characterize enzyme activity—a curve of initial velocity vs. substrate concentration, sometimes referred to as a Michaelis-Menten plot, with an inset Lineweaver-Burk plot. This article includes the following techniques:

NettetIn biochemistry, the Lineweaver–Burk plot (or double reciprocal plot) is a graphical representation of the Michaelis–Menten equation of enzyme kinetics, described by … NettetFigure 1 Lineweaver-Burk plot for determination of Km and Vma x. (0) experimental points. In problem (i) the abscissa has been drawn at a value of l/V ~ O, so that the intercept on this abscissa =b -1/Km. In problem (ii) insufficient space has been left on the left-hand side of the
NettetUse. The Lineweaver-Burk plot was widely used to determine important terms in enzyme kinetics, such as K m and V max before the wide availability of powerful computers and … NettetToday we will look at the Lineweaver-Burk plot, which is central in enzyme kintetics. A typical curve of enzyme kinetics plots the velocity or rate of reacti...
NettetKinetic constants for free and immobilized enzyme were also determined by using the Lineweaver-Burk plot.The Km values of the free and immobilized enzymes were … NettetHanes–Woolf plot. In biochemistry, a Hanes–Woolf plot, Hanes plot, or plot of against , is a graphical representation of enzyme kinetics in which the ratio of the initial substrate concentration to the reaction velocity is plotted against . It is based on the rearrangement of the Michaelis–Menten equation shown below:
NettetIt can be seen that the Lineweaver–Burk equation gives an unequal distribution of points and greater emphasis to the points at low substrate concentration that are subject to the greatest...
NettetLineweaver-Burk-plottet er en simpel linearisering, som tillader grafisk at vurdere, hvorvidt et kinetisk datasæt følger Michaelis-Menten-kinetik . Michaelis-Menten-ligningen kan beskrives som: Hvor V er reaktionshastigheden, Km er Michaelis-konstanten, Vmax er den maksimale reaktionshastighed og [ S] er substratkoncentrationen. the organikNettetLineweaver Burk plots are another way of representing the data from Michaelis-Menten saturation curves. It originates from the Lineweaver Burk equation, which is derived from the Michaelis-Menten equation below: V 0 = (V max x [S]) / (K M + [S]) The reciprocal of this equation is: 1 / V0 = (KM / Vmax [S]) + (1 / Vmax) the organic tshirtNettetTypes of inhibitors according to lineweaver-burk plot.
