To find the chemical formula of ketohexose, we need to understand what ketohexose is. Ketohexose is a type of monosaccharide, which is a simple sugar molecule that consists of carbon, hydrogen, and oxygen atoms.
Monosaccharides have the general chemical formula CnH2nOn, where "n" represents the number of carbon atoms. In the case of ketohexose, "n" is 6, meaning it has 6 carbon atoms.
Now, let's identify the "keto" group in ketohexose. The keto group is a functional group (-C=O) that indicates the presence of a ketone in the compound. In ketohexose, the keto group is present on the second carbon atom.
Combining this information, we can determine the chemical formula of ketohexose. With 6 carbon atoms, the formula would be C6H12O6. However, because ketohexose has a keto group, the formula becomes C6H12O5, as one oxygen atom is used in the keto group.
Therefore, the chemical formula of ketohexose is C6H12O5.
