What exactly are glycolipids? Well, Glycolipids are biological molecules that contain a lipid molecule attached via glycosetic bond to a sugar moiety. And that sugar moie can be a single sugar or it can be some type of polysaccharide many sugars. 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.
