| Comments |
"Ion channels are integral membrane proteins
spanning the lipid bilayer and necessarily communicating
with both aqueous phases. Conceptually
they may be considered as enzymes, in that they
reduce the energies of transmembrane ionic diffusion
from the 250 kJ/mol above to values in the
range of 20 kJ/mol [primary source] - a rate enhancement of
about 10^39" |
