Multiple Choice

Which type of lipid contains alcohol functional groups as part of its structure?

Triacylglycerols

Sphingolipids

Steroids

Glycerophospholipids

Verified step by step guidance

Understand the structure of glycerophospholipids: These lipids consist of a glycerol backbone, two fatty acid chains, and a phosphate group attached to an alcohol group. The alcohol functional group is part of the phosphate head group, which makes glycerophospholipids amphipathic.

Compare glycerophospholipids to triacylglycerols: Triacylglycerols consist of a glycerol backbone and three fatty acid chains, but they lack a phosphate group or alcohol functional groups in their structure.

Compare glycerophospholipids to sphingolipids: Sphingolipids have a sphingosine backbone instead of glycerol, and while they may contain functional groups, they do not have the same alcohol functional groups as glycerophospholipids.

Compare glycerophospholipids to steroids: Steroids are composed of a fused ring structure (cyclopentanoperhydrophenanthrene) and do not contain alcohol functional groups as part of their primary structure.

Conclude that glycerophospholipids are the correct answer because their structure includes alcohol functional groups as part of the phosphate head group, distinguishing them from the other lipid types listed.
