검증된 단계별 안내1
Step 1: Begin by understanding the primary functions of lipids in biological systems. Lipids are a diverse group of biomolecules that include fats, oils, phospholipids, and steroids. Their functions are distinct from proteins and nucleic acids.
Step 2: Recall that lipids are primarily involved in energy storage. Lipids, such as triglycerides, store energy in the form of long hydrocarbon chains, which can be broken down to release energy during metabolic processes.
Step 3: Evaluate the other options provided in the question. Transporting oxygen in blood is a function of hemoglobin, a protein, not lipids. Catalyzing biochemical reactions is a function of enzymes, which are also proteins. Genetic information storage is a function of nucleic acids, such as DNA and RNA.
Step 4: Compare the correct function of lipids (energy storage) with the incorrect options. Lipids are not directly involved in oxygen transport, catalysis, or genetic information storage, which are functions of other biomolecules.
Step 5: Conclude that the correct answer is 'Energy storage,' as this is a well-established function of lipids in biochemistry.
