What does C6H12O6 represent?

C6H12O6 represents the molecular formula for glucose, which is a type of sugar. Glucose is a simple sugar that serves as a primary source of energy for many living organisms. The formula indicates that each molecule of glucose consists of six carbon atoms (C), twelve hydrogen atoms (H), and six oxygen atoms (O), which is characteristic of monosaccharides.

Understanding the structure of glucose is key in various biological processes, such as cellular respiration and photosynthesis, where it is either produced or utilized for energy. In contrast, the other substances listed have different molecular formulas and functions: oxygen is represented as O2, carbon dioxide as CO2, and hydrogen peroxide as H2O2. Therefore, recognizing that C6H12O6 corresponds to sugar, specifically glucose, is essential for identifying its role in biological systems.
