Glycolipids and GlycoproteinsWatch
Glycoproteins are intrinsic - 5th paragraph on page 104 "Glycoproteins are intrinsic proteins"
Glycolipids are extrinsic - 10th paragraph on page 204 "they [glycolipids] are lipids with attached carbohydrate (sugar) chains". Therefore, as lipids are extrinsic by nature, hence a phospholipid bilayer (2 layers of extrinsic lipids), a lipid with a carbohydrate chain attached remains extrinsic.
Hope this clears this up!
