Classify lipids
Free printable Biology science worksheet for "Classify lipids" — practice biomolecules. No-prep, print or assign online.
High school students classify lipids into their major categories — triglycerides, phospholipids, steroids, and waxes — and examine how the structure of each type relates to its biological function. This Life Science worksheet on Biomolecules supports deeper understanding of how lipids serve as energy stores, membrane components, and chemical messengers in living systems. Classifying lipids is a foundational skill for biochemistry, cell biology, and understanding metabolic processes at the molecular level.
Learning objectives
- Classify lipids into major categories and identify a defining structural feature of each
- Explain the biological function of each major lipid type in living organisms
- Connect lipid structure to function using examples from cellular membranes or energy storage
