In glycolipids, what is attached in place of a phosphate group?

Explanation:
In glycolipids, the lipid carries a carbohydrate as the head group instead of a phosphate. The sugar moiety is covalently attached to the lipid (often to ceramide in sphingolipids or to glycerol in other lipids) and protrudes outward from the membrane, enabling cell recognition. So the attached group in place of a phosphate is a carbohydrate. Cholesterol, proteins, and nucleic acids aren’t the head groups of glycolipids.
