검증된 단계별 안내1
Understand the definition of lipids: Lipids are a diverse group of hydrophobic molecules, primarily composed of carbon and hydrogen atoms. They include fats, oils, waxes, certain vitamins, hormones, and most non-protein membrane components.
Identify the common types of lipids: The main categories of lipids include triglycerides, phospholipids, and steroids. Each of these plays a distinct role in biological systems.
Examine the characteristics of proteins: Proteins are large, complex molecules made up of amino acids. They perform a vast array of functions within organisms, including catalyzing metabolic reactions, DNA replication, and transporting molecules.
Compare proteins with lipids: Proteins differ from lipids in structure and function. While lipids are primarily involved in energy storage, structural components of cell membranes, and signaling, proteins are involved in catalysis, structural support, and regulation.
Conclude which option is not a lipid: Based on the definitions and characteristics, proteins do not fit the classification of lipids, as they are composed of amino acids and serve different biological functions.

To study the effect of lipids on heart disease, researchers fed mice diets including cholesterol (Control), cholesterol with trans fatty acids (Trans), or cholesterol with cis fatty acids (Cis). After 8 weeks, they examined them for atherosclerosis—the narrowing of arteries that is a leading cause of heart attacks. Data from their observations of atherosclerotic lesions are provided below (* means 𝑃<0.05; see BioSkills 3). What do these data reveal concerning lipid structure and heart disease in mice?
