<!-- Page Title: Lipid Bilayers -->
<h2>Introduction</h2>
<p>
    These scripts show the structure of the phospholipids in a bilayer. (Based
    on a molecular model of the bilayer generated by molecular dynamic
    calculations, Heller et al. (1993) J.Phys.Chem. <strong>97</strong>: 8343)
</p>
<br>

<h2>Bilayer 1</h2>
<p>
    Here is the arrangement of phospholipids in a bilayer. Notice the close
    packing of the fatty acyl chains.
</p>
<!-- JSMol Window Container -->
<div id="jsmolWindow1"></div>
<!-- UI Control Box -->
<div style="text-align: center;">
    <!-- give the button a right margin for spacing -->
    <button type="button" id="resetBtn1" style="margin-right: 10px;">Reset</button>
    <input type="checkbox" id="spinBox1"> Spin On/Off
</div>
<br>

<h2>Top View</h2>
<p>
    Here is a view from the top. Note the close packing of the polar head
    groups.

<div style="text-align: center; margin-top: 10px;">
    <button type="button" id="resetBtn2" style="margin-right: 10px;">Reset</button>
    <input type="checkbox" id="spinBox2"> Spin On/Off
</div>
<br>

<h2>Crystal Bilayer</h2>
<p>
    The bilayer can exist in a highly ordered crystalline state, as shown here.
</p>
<div id="jsmolWindow3"></div>
<div style="text-align: center; margin-top: 10px;">
    <button type="button" id="resetBtn3" style="margin-right: 10px;">Reset</button>
    <input type="checkbox" id="spinBox3"> Spin On/Off
</div>
<br>

<h2>Fluid Bilayer</h2>
<p>
    Or, the bilayer can exist in a more disordered fluid state, as shown here.
    The fluid state is more representative of the state of the phospholipids in
    a natural membrane.
