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.
Explanation : A secondary amine is an amine (nitrogen atom) that is attached to two carbon-containing groups (alkyl groups or aryl groups). The nitrogen in ephedrine is attached to two alkyl groups, making it a secondary amine. Primary amines are generally written as.he correct answer is arrow B. An amide group is a carbonyl group with a nitrogen that is in the alpha position (directly attached to the carbonyl carbon). Penicillin has two different amide groups in its chemical structure, but only one has an arrow pointing to it in the diagram.
