Glucose ($\text{C}_6\text{H}_{12}\text{O}_6$) is a six-carbon monosaccharide containing an aldehyde group, which classifies it as an aldohexose. It possesses five hydroxyl ($\text{-OH}$) groups and functions as a reducing sugar. An aldopentose, on the other hand, is a five-carbon sugar with an aldehyde group (such as ribose). Therefore, the statement that glucose is an aldopentose is incorrect.
