Advection of particles to form streamlines of the electric field.
The acetylcholinesterase enzyme is represented here as a smooth twisting ribbon
that traces its way along the chain of amino acids that make up the molecule.
Settled deep within the catalytic center of the enzyme, an acetylcholine molecule
is rendered as a space- filling model. The electrostatic potential appears as
a glowing aura with negative values colored red and positive values colored blue.
Converging streamlines near the entrance to the enzyme's interior illustrate how
electrostatic forces guide positively charged molecules toward the active site.
