| The retardation of proton escape from the membrane surface was previously explained by the damping effect of immobile pH buffer at the surface. |
| A Dalton, also known as an atomic mass unit, is roughly the mass of a single proton or neutron. |
| Several years ago, it appeared that the only solid acids that could support high proton transport were those based on sulfates or selenates. |
| Identical results were obtained by Willis and Szabo using tyrosine in the presence of acetate and other proton acceptors. |
| This indicates that the bound azide is required to detect the 410-nm signal and suggests that azide plays the role of the proton acceptor. |
| The first step is the addition of the proton to the pi bond of the alkene or alkyne, acting as the electron source. |
