[[File:FructoseP2Split.svg|thumb|Role of iminium and enamines in splitting of [[fructose 2,6-bisphosphate]].]]
Nature processes (makes and degrades) [[sugar]]s using enzymes called [[aldolase]]s.  These enzymes act by reversible formation of enamines.<ref>{{cite journal |doi=10.1021/ar0300468 |title=Enamine-Based Organocatalysis with Proline and Diamines: The Development of Direct Catalytic Asymmetric Aldol, Mannich, Michael, and Diels−Alder Reactions |date=2004 |last1=Notz |first1=Wolfgang |last2=Tanaka |first2=Fujie |last3=Barbas |first3=Carlos F. |journal=Accounts of Chemical Research |volume=37 |issue=8 |pages=580–591 |pmid=15311957 }}</ref><ref>{{cite journal |doi=10.1021/cr0684016 |title=Asymmetric Enamine Catalysis |date=2007 |last1=Mukherjee |first1=Santanu |last2=Yang |first2=Jung Woon |last3=Hoffmann |first3=Sebastian |last4=List |first4=Benjamin |journal=Chemical Reviews |volume=107 |issue=12 |pages=5471–5569 |pmid=18072803 }}</ref>
