Proposed Title: Gramicidin Channel in Lipid Bilayer
 |
|
Two copies of the gramicidin protein are shown here () arranged as they are believed to be when they form a channel through a lipid bilayer membrane[1]. The shape of the protein is shown transparent (ghostly), and a backbone trace connecting the alpha carbon atoms of each amino acid chain is opaque (solid).
- Show of the gramicidin protein chains.
- (Most hydrogen atoms are omitted.)
- Show . Notice how the hydrophobic lipid "tails" exclude water.
- Water passes .
