Difference Between Hemiacetal and Hemiketal
WebWith the use of the dipolar-dephasing spectral editing technique, this resonance was identified as a hemiketal carbon. Hence, the ketone–hemiketal tautomeric reaction has been shown to occur in the solid state and the formation of a cyclic hemiketal has been proven by solid-state NMR.

Fructose is both a ketone at C-2 and an alcohol at C-5. These two groups can react with each other to form a cyclic hemiketal (fructofuranose). In the hemiketal, the anomeric carbon, C-2, has become chiral. It can have the OH group … common hep b medication
