NettetEn biochimie, le diagramme de Lineweaver-Burk est une représentation graphique permettant d'étudier la cinétique de réactions enzymatiques. Il est nommé ainsi d'après … NettetA typical curve of enzyme kinetics is a plot of a plot of velocity of reaction vs substrate concentration. As the substrate concentration increases the velocity of the reaction increases until it...

NettetLineweaver–Burk (L–B) plots, obtained from the urea–urease hydrolysis assay, were used to calculate Michaelis–Menten constant (Km) values for free and immobilized ureases. 2. The concentrations of urea were in the range of 0.14–1.4 mMand 0.062–0.312 mMfor UCG and free urease in PBS solution, respectively. 3. Nettet5. mar. 2024 · For a Lineweaver-Burk, the manipulation is using the reciprocal of the values of both the velocity and the substrate concentration. The inverted values are … The Lineweaver-Burk plot derives from a transformation of the Michaelis-Menten equation , in which the rate is a function of the substrate concentration and two parameters , the limiting rate, and , the Michaelis constant. Taking reciprocals of both sides of this equation it becomes as follows: Se mer In biochemistry, the Lineweaver–Burk plot (or double reciprocal plot) is a graphical representation of the Lineweaver–Burk equation of enzyme kinetics, described by Hans Lineweaver and Dean Burk in 1934. The Lineweaver–Burk … Se mer $${\displaystyle [S]}$$: substrate concentration. The independent axis of a Lineweaver-Burk plot is the reciprocal of substrate concentration, $${\displaystyle {\frac {1}{[S]}}}$$ Se mer When used for determining the type of enzyme inhibition, the Lineweaver–Burk plot can distinguish competitive, pure non-competitive and uncompetitive inhibitors. The various modes of inhibition can be compared to the uninhibited reaction. Competitive Inhibition Se mer • Michaelis–Menten kinetics • Eadie–Hofstee diagram • Hanes–Woolf plot Se mer The plot provides a very useful graphical method for analysis of the Michaelis–Menten equation, as it is difficult to determine precisely the Vmax of an enzyme-catalysed … Se mer While the Lineweaver-Burk is useful for determining important variables in enzyme kinetics, it is prone to error. The y-axis of the plot takes the reciprocal of the rate of reaction, meaning small errors in measurement are more noticeable. Additionally, the … Se mer • NIH guide, enzyme assay development and analysis Se mer frog high school
