Glycerol backbone

Ester bonds

Phosphate group

Verified step by step guidance

Understand the structural components of triglycerides and phospholipids. Triglycerides consist of a glycerol backbone attached to three fatty acid chains via ester bonds. Phospholipids consist of a glycerol backbone, two fatty acid chains, and a phosphate group attached to the third position of the glycerol.

Compare the components of triglycerides and phospholipids. Both contain fatty acid chains, a glycerol backbone, and ester bonds. However, phospholipids uniquely contain a phosphate group, which is absent in triglycerides.

Analyze the question. It asks for the structural component that is NOT found in both triglycerides and phospholipids. This means identifying the component that is exclusive to one of the molecules.

Recognize that the phosphate group is the distinguishing feature of phospholipids and is not present in triglycerides. Therefore, it is the correct answer to the question.

Conclude that the phosphate group is the structural component that is NOT found in both triglycerides and phospholipids, as it is unique to phospholipids.
