what is an amide?
An amide is a class of organic compounds containing a nitrogen atom attached to an acyl group. Amides are considered a derivative of carboxylic acids and can also be prepared from amines, anhydrides, esters, and nitriles. All peptide linkages in proteins are amides. A carboxylic acid and an amine react to form amide. Organic acids are characterized by an end carbon bonded to a carbonyl group (-C=O) and a hydroxyl group (-OH), collectively written as -COOH. The amines have organic groups bonded to a nitrogen atom.
