Dnp reaction mechanism
WebThe mechanism of the iodoform reaction is that of alpha-halogenation of a carbonyl compound under basic conditions, followed by nucleophilic displacement of the resulting … In living cells, DNP acts as a proton ionophore, an agent that can shuttle protons (hydrogen cations) across biological membranes. It dissipates the proton gradient across the mitochondria membranes, collapsing the proton motive force that the cell uses to produce most of its ATP chemical energy. Instead of producing ATP, the energy of the proton gradient is lost as heat. DNP is often used in biochemistry research to help explore the bioenergetics of chemiosmotic and …
