Binding curve biochem

WebIC 50 is a quantitative measure that indicates how much of a particular inhibitory substance (e.g. drug) is needed to inhibit, in vitro, a given biological process or biological component by 50%. [1] The biological component could be an enzyme, cell, cell receptor or microorganism. IC 50 values are typically expressed as molar concentration . WebMar 15, 2024 · The cyan curve might reflect the binding of a ligand to the T form of a macromolecule, with K D = 100 uM (low affinity), for example. The binding curve looks linear, but it really is just the initial part of a hyperbolic binding cure. Likewise, the magenta curve reflects the binding of a ligand to the R form of the macromolecule with K D = 10 ...

WebSep 8, 2024 · An oxygen-binding curve is a plot that shows fractional saturation versus the concentration of oxygen. By definition, fractional saturation indicates the presence of binding sites that have oxygen. … WebA sigmoidal curve shows that oxygen binding is cooperative; that is, when one site binds oxygen, the probability that the remaining unoccupied sites that will bind to oxygen will increase. The importance of cooperative behavior is that it allows hemoglobin to be more efficient in transporting oxygen. Why is allosteric enzyme sigmoidal curve?
