Now, glycolipids actually resemble a type of phospholipid we call the spingolipids. And that's because glycolipids also contain the sphingocene molecule, just like spingolipids do. And this is the general way that we represent a glycolipid. So this is using boxes and this is using a slightly different format. And we actually use this pictorial representation in just a moment. So basically, the brown structure is the sphingosine, this is the fatty acid and this is the sugar moiety.
