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.
The amides contain nitrogen, and nitrogen composes about 16% of the protein atomic content. These proteins are created in the body by condensation of amino acids under the influence of enzyme catalysts, using patterns or direction from the nucleic acids in the cells.
