All carbons except one have an OH group. The remaining carbon has a double bond to oxygen, making it an aldehyde or ketone. For example, the Fisher projection of glucose looks like this: C H- H- -ОН НО -ОН -HO- CH2OH Because a simple sugar has both a carbonyl carbon and built-in nucleophiles, a reaction can occur within the molecule itself to create the hemi-acetal form of the sugar.
