Lipids and Biomembranes

ID #1637

In the diagram on PDF page 5, slide 2 (full lecture slides), all of the lipids have a head and two have oligosaccharide chains attached to the head. if the "red" heads of the other lipids are phosphate groups, what constitutes the head of the glycolipids? If it is a carbohydrate, why is it so much larger than the other "purple" monosaccharides in the oligosaccharide chain?

The "red" parts of both the phospholipids and glycolipids in this picture would simply be representing the polar backbone molecule. This is an incomplete picture at best, and should only be used as an introduction to glycolipids, not a true representation of a biological membrane.
