Verified step by step guidance

Step 1: Begin by understanding the definition of lipids. Lipids are a diverse group of hydrophobic molecules that include fats, oils, and certain types of biological molecules. They are primarily composed of carbon, hydrogen, and oxygen atoms.

Step 2: Review the types of lipids commonly found in biological systems. The three main types are triglycerides, phospholipids, and steroids. Each has distinct structures and functions: Triglycerides are energy storage molecules, phospholipids are key components of cell membranes, and steroids include hormones like cholesterol.

Step 3: Analyze the options provided in the question. The first option (enzymes, hormones, and antibodies) refers to proteins and not lipids. The second option (monosaccharides, disaccharides, and polysaccharides) refers to carbohydrates. The third option (amino acids, nucleotides, and fatty acids) includes building blocks of proteins, nucleic acids, and lipids but does not represent types of lipids.

Step 4: Compare the correct answer (triglycerides, phospholipids, and steroids) to the other options. This list accurately represents three types of lipids, as each is a distinct category within lipid biochemistry.

Step 5: Conclude that the correct answer is 'Triglycerides, phospholipids, and steroids,' as these are the three main types of lipids found in biological systems.
