Verified step by step guidance1
Understand the structure of sphingolipids: Sphingolipids are a class of lipids that have a sphingoid base backbone, not a glycerol backbone. This distinguishes them from glycerophospholipids.
Identify the types of linkages in sphingolipids: Sphingolipids can have either a phosphodiester linkage or a glycosidic linkage to their polar head group. This is a key feature that differentiates them from other lipid types.
Evaluate option A: Not all sphingolipids are phospholipids. While some, like sphingomyelins, are phospholipids, others, such as glycosphingolipids, are not.
Evaluate option B: Sphingolipids do not all contain a carbohydrate backbone. Instead, they have a sphingoid base backbone, and only some, like glycosphingolipids, have carbohydrate groups attached.
Evaluate option D: Sphingolipids do not contain a glycerol molecule backbone. This is a characteristic of glycerophospholipids, not sphingolipids.
