Which lipid class contains both sphingosine and a carbohydrate group?

### Why this is right A glycosphingolipid combines a sphingosine-based lipid structure with one or more carbohydrate groups. These molecules are membrane lipids involved in cell-surface interactions. ### The other options - **Triacylglycerol**: contains glycerol esterified to three fatty acids and is primarily a storage lipid. - **Steroid**: has a characteristic fused-ring structure. - **Terpene**: belongs to a broad class built from isoprene units. ### Terms - **Sphingosine**: a long-chain amino alcohol that forms the backbone of many sphingolipids. - **Glycosphingolipid**: a sphingolipid with an attached carbohydrate. ### Remember The name combines glyco, meaning carbohydrate, with sphingolipid.
