                                Despite a common misconception, glucose is unequivocally a six-carbon sugar, scientifically classified as a hexose. This is fundamentally different from a C5 sugar, known as a pentose, which has five carbon atoms in its structure. The correct classification is essential for understanding its metabolic role.
