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 . WebAs a matter of fact, you can tell a remarkable amount about how an enzyme works, and about how it interacts with other molecules such as inhibitors, simply by measuring how quickly it catalyzes a reaction under a series of different conditions.
Web23 de dez. de 2024 · Overall, affinity and specificity of individual RNA–protein interactions depend on the structural features of both RNA and RNA-binding modules and on the level of conformational flexibility of these interacting partners. 3. Disordered linkers combine and coordinate multiple RNA-binding modules within a protein. WebHemoglobin is a protein in red blood cells (RBCs) that carries oxygen. Almost 30\% 30% of the mass of RBCs is made up by hemoglobin. This allows RBCs to carry much more oxygen than could otherwise be dissolved into blood. A researcher studies the oxygen dissociation curves of normal adult hemoglobin (HbA), fetal hemoglobin (HbF), and myoglobin ...
