Nettet7. mar. 2024 · 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. [1] The Lineweaver–Burk plot for inhibited enzymes can be compared to no inhibitor to determine how the inhibitor is competing …
NettetAccording to the Lineweaver-Burk plot the Vmax is reduced during the addition of a non-competitive inhibitor, which is shown in the plot by a change in both the slope and y-intercept when a non-competitive inhibitor is added.

NettetQuotient velocity plot for mixed type inhibition. The lines were drawn in accordance with Equation (6). The following values of param-eters were used: K m = 1, K i = 2, and K’ i = 4. The substrate concentration is indicated by each line. Table1. Values of intersection points and slopes of quotient velocity plots. Inhibition type department of human services cleveland tnNettetSecondary plots and Dixon plots enable the inhibitor constant Ki to be calculated and help distinguish between mechanisms which give identical primary Lineweaver-Burk plots. These types of inhibition are used in biochemical research and have applications in medicine and agriculture. fhia bbb ratingNettet1. sep. 2024 · When used for determining the type of enzyme inhibition, the Lineweaver–Burk plot can distinguish competitive, non-competitive and uncompetitive inhibitors. Competitive inhibitors have the same y-intercept as … fhi 360 research utilizationNettetMost general biochemistry textbooks present enzyme inhibition by showing how the basic Michaelis-Menten parameters K(m) and V(max) ... correspond to the y-intercept and slope of the Lineweaver-Burk plot, respectively.
