But in the case of spingolipids, the platform molecule, that backbone is a much more complex alcohol molecule that basically looks like this. So instead of having this three carbon alcohol, we have this more complex alcohol in which we have a primary alcohol, a secondary alcohol, we have this long unsaturated hydrocarbon component that contains this double bond. And we also have this amino group that contains a positive charge. This is this fingersine that acts as a platform molecule that attaches all these other components. So one example of a single lipid that we're going to find around the membranes of nervous cells. So nerve cells is basically a finger myelin molecule.
