Question
### Molecular Structure and Lipid Classification The image shows a structural formula of a lipid molecule. To the right of the molecule is a question: "The molecule at the left is an example of which lipid?" Possible answers are listed as follows: a) wax b) terpene c) steroid d) sphingolipid e) glycerophospholipid ### Explanation: #### Molecular Structure: - The molecule features a long hydrocarbon tail, likely indicative of fatty acid chains, terminating at an ester linkage. - It contains two ester bonds connecting fatty acid tails to a glycerol backbone. - A phosphate group is present, attached at the third carbon of the glycerol, which is a characteristic element in certain types of lipids. This structure is typical of a **glycerophospholipid**, a category of phospholipids that play a critical role in cell membrane composition. The presence of the phosphate group linked to glycerol is a key identifying feature. These biomolecules are pivotal in forming the lipid bilayers of cells, contributing significantly to cellular structure and function.
