So in this video, we're going to introduce the simple idea of a glycolipid. A glycolipid is just a hybrid molecule; it's a combination of two different types of molecules. The first is going to be a lipid molecule and the second is going to be carbohydrates or small sugars. "Glyco" is the prefix referring to sugars and, of course, "lipids" are referring to lipids. Glycolipids are hybrid molecules made up of lipids, covalently linked or covalently attached to small sugars.

If we take a look at our image down below, notice that we do have this oligosaccharide right here, and notice that the oligosaccharide is quite heterogeneous, so it's made up of many different types of monosaccharide units. Also, notice that the oligosaccharide is covalently attached to a lipid here, and that is what makes this glycolipid.

We will be talking more about glycolipids throughout our course, especially when we're talking about biosignaling later in our course. We will also talk a lot more about lipids later in our course when we're focusing on lipids as well. But for now, this is the conclusion to our simple idea of glycolipids, and we will see you in our next video when we talk about glycoproteins.
