Which of the following represents a lipid molecule?
Understand the Problem
The question is asking to identify which of the provided chemical structures represents a lipid molecule. This requires recognizing the characteristics of lipid structures, such as the presence of long hydrocarbon chains or specific functional groups.
Answer
The second image with four carbon rings is a lipid molecule.
The second image with the structure of four carbon rings represents a lipid molecule.
Answer for screen readers
The second image with the structure of four carbon rings represents a lipid molecule.
More Information
Lipid molecules can include structures like four carbon rings (steroids), triglycerides, or phospholipids. The second image resembles a steroid.
Tips
A common mistake is confusing simple sugars or amino acids with lipids. Lipids often have long hydrocarbon chains or ring structures.
