WebThe k inact /K I is a rate constant describing the efficiency of covalent bond formation resulting from the potency (K I) of the first reversible binding event and the maximum potential rate (k inact) of inactivation. In this perspective, it is proposed that the k inact /K I should be employed as a critical parameter to identify covalent ... WebDec 5, 2024 · Under appropriate conditions, the reversible covalent bonds usually split into reversible groups, which are sufficiently active to reconstruct and the reversibility of a chemical bond is determined by its reactivity of forward and reverse reactions [17]. In principle, all chemical reactions have a certain degree of reversibility.
