1. Simple sugars are defined as polyhydroxy aldehydes/ketones. 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. Propose a mechanism for this reaction when it occurs in an aqueous solution. C -- CH2OH он в CH2OH HO- H H НО H. ОН Н and ОН Н HO- он Он а OH H H- ОН OH H ОН ČH2OH
