WebThe protonation steps are at least partially rate-limiting, therefore the steady-state rates of P450 catalysis are usually slower in deuterated solvent (D 2 O) by a factor of 1.5-3. However, in several P450 systems a pronounced inverse kinetic solvent isotope effect (KSIE ∼0.4-0.7) is observed, where the reaction is faster in D 2 O. WebWhat solvents are in it and how much? The higher the solvent content, the greater the risk. The risk is also greater for solvents that are more toxic, and those that produce more vapour. - Be aware that many solvents can produce a lot of vapour even at room temperature. Consider the overall effect if there is more than one solvent involved.
