In organic chemistry, an amide, [1][2][3] also known as an organic amide or a carboxamide, is a compound with the general formula R−C (=O)−NR′R″, where R, R', and R″ represent any group, typically organyl groups or hydrogen atoms [4][5] The amide group is called a peptide bond when it is part of the main chain of a protein, and an
Amide | Definition, Formula, Examples, Uses, Facts | Britannica
