Amides
- The nitrogen variant of an ester.
Draw a C double-bond O. Add an N bound to the carbon and an R bound to the N. As the third bond on nitrogen, add a hydrogen, and as the fourth bond on carbon add another R group.
Amide bonds are also called peptide bonds, because they are the bonds that join amino acids together in primary protein structure, the most basic structure of proteins. They are formed by the reaction of amines and carboxylic acids.
