A protonophore, also known as a proton translocator, is an ionophore that moves protons across lipid bilayers or other type of membranes. This would otherwise not occur as protons cations (H ) have positive charge and hydrophilic properties, making them unable to cross without a channel or transporter in … See more The facilitated transport of protons across the biological membrane by anionic protonophore is achieved as follows. 1. The anionic form of the protonophore (P ) is adsorbed onto one side (Positive) of the biological … See more • Chemiosmosis See more WebFeb 17, 1995 · The protonophore, FCCP (1 microM), produced an acidification comparable to that produced by glutamate. Application of glutamate to FCCP-treated cells, returned pHi to resting levels. This alkaline shift resulted from a glutamate-induced membrane depolarization that removed the driving force across the plasmalemma for H+ entry via …

WebDec 18, 2009 · In such a system, addition of protonophore (FCCP) resulted in a transmembrane H + flux generating an electric potential difference across BLM, the more acidic compartment being negatively charged. It was found that palmitate and a penetrating cation added together can effectively substitute for FCCP. In these experiments, … WebRottlerin has been widely accepted as a specific inhibitor of protein kinase C delta (PKC delta); however, recent data suggest that the specificity of this com
WebIt is a nitrile, hydrazone and protonophore. In general, CCCP causes the gradual destruction of living cells and death of the organism, [1] [2] although mild doses inducing partial decoupling have been shown to increase median and maximum lifespan in C. elegans models, suggesting a degree of hormesis.
