The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.14187-32-7, Name is Dibenzo-18-crown-6, molecular formula is C20H24O6. In a Article£¬once mentioned of 14187-32-7, SDS of cas: 14187-32-7
Thirteen cationic ionophores: Their acute toxicity, neurobehavioral and membrane effects
Thirteen cationic ionophores (12-Crown-4, 15-Crown-5, 18-Crown-6, Dibenzo 18-Crown-6, Dicyclohexano 18-Crown-6, 24-Crown-8, Dicyclohexano 24-Crown-8, Lasalocid, Hexacyclen trisulfate, Chiral binapthol, Valinomycin, Monensin, and A-23187) were evaluated for acute toxicologic properties, including lethality and neurobehavioral effects in multiple species (rats, rabbits, and mice) by multiple routes, skin and eye irritation and effects on membrane permeability to physiologic cations. Attention was focused on determining minimum neurobehavioral effect levels and characterizing the spectrum of these effects at different dose levels. While LD50’s followed one pattern, this was not the case with other effects. Cluster and factor analysis suggest that, though the primary mechanism of action is alteration of membrane permeability to specifi-cations (qualitative types of activity correlate with the results of membrane permeability studies), which ions are provided an increased passage varies with ring size and charge dispersion. In the intact animal absorption markedly modifies these results.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 14187-32-7, you can also check out more blogs about14187-32-7
