Multiple Choice

What is the primary structural difference between a triglyceride and a phospholipid?

A triglyceride is amphipathic, while a phospholipid is completely hydrophobic.

A triglyceride is a component of cell membranes, while a phospholipid is used primarily for energy storage.

A triglyceride has three fatty acid chains, while a phospholipid has two fatty acid chains and a phosphate group.

A triglyceride contains a glycerol backbone, while a phospholipid does not.

Verified step by step guidance

Identify the basic structure of a triglyceride: A triglyceride consists of a glycerol backbone bonded to three fatty acid chains through ester linkages.

Identify the basic structure of a phospholipid: A phospholipid also has a glycerol backbone, but it is bonded to two fatty acid chains and one phosphate group, which is often linked to additional polar groups.

Compare the number of fatty acid chains: Triglycerides have three fatty acid chains, whereas phospholipids have two.

Identify the presence of a phosphate group: Phospholipids contain a phosphate group, which is absent in triglycerides. This phosphate group contributes to the amphipathic nature of phospholipids, making them key components of cell membranes.

Summarize the primary structural difference: The main structural difference is that triglycerides have three fatty acid chains, while phospholipids have two fatty acid chains and a phosphate group, which is crucial for their function in biological membranes.
