Verified step by step guidance

Step 1: Understand the structure of glucose ($\mathrm{C_6H_{12}O_6}$). Glucose is a monosaccharide with six carbon atoms, making it a hexose. It also contains an aldehyde functional group, which classifies it as an aldose.

Step 2: Analyze the term 'Pentose'. A pentose is a monosaccharide with five carbon atoms. Since glucose has six carbon atoms, it cannot be classified as a pentose.

Step 3: Analyze the term 'Ketohexose'. A ketohexose is a hexose (six-carbon sugar) that contains a ketone functional group. Glucose contains an aldehyde group, not a ketone group, so it is not a ketohexose.

Step 4: Analyze the term 'Aldohexose'. An aldohexose is a hexose that contains an aldehyde functional group. Since glucose has six carbon atoms and an aldehyde group, it is correctly classified as an aldohexose.

Step 5: Analyze the term 'Disaccharide'. A disaccharide is a carbohydrate composed of two monosaccharide units joined by a glycosidic bond. Glucose is a single monosaccharide, so it is not a disaccharide.
