... Imines are created when a carbon of a ketone or aldehyde is attacked by a (nucleophilic) amine; as shown above, the inter-mediate is an amine with an alcohol on the α-carbon, which will eventually rearrange into a C=N bond. This final product is the imine, or Schiff base. Note the similarity of the ...

Fatty acid synthesis
Fatty acid synthesis is the creation of fatty acids from acetyl-CoA and malonyl-CoA precursors through action of enzymes called fatty acid synthases. It is an important part of the lipogenesis process, which – together with glycolysis – functions to create fats from blood sugar in living organisms.
