Thiol vs thioether

WebThe interconversion between thiols and disulfide groups is a redox reaction: the thiol is the reduced state, and the disulfide is the oxidized state. Notice that in the oxidized (disulfide) … WebDec 10, 2016 · The acyl phosphate reaction is a means of generating a thioester. The reaction works in reverse as well - the energy of a thioester bond (Δ G °′ = −7.5 kcal/mol for hydrolysis) can be conserved in the terminal phosphoanhydride bond of ATP. Other types of thioesters that occur in biochemical processes are indicated.
