In chemistry, the term amide (/ˈæmaɪd/ or /ˈæmɪd/ or /ˈeɪmaɪd/) is a compound with the functional group RnE(=O)xNR2, where n and x may be 1 or 2, E is some element, and each R represents an organic group or hydrogen. It is a derivative of an oxoacid RnE(=O)xOH with an hydroxy group –OH replaced by an amine group –NR2. Some important subclasses are * carboxamides, or organic amides, where E = carbon, with the general formula RC(=O)NR2. * phosphoramides, where E = phosphorus, such as R2P(=O)NR2 * sulfonamides, where E = sulfur, namely RS(=O)2NR2 The term amide may also refer to

  • Grupa amidowa (wiązanie amidowe) – grupa funkcyjna, charakterystyczna dla amidów, składająca się z fragmentu kwasu tlenowego, w którym jedna grupa hydroksylowa została zastąpiona grupą aminową (wolną −NH2 albo podstawioną, czyli −NHR lub −NR2). W nazwie grupy można uwzględnić rodzaj reszty kwasowej, na przykład grupa karboksyamidowa, sulfonamidowa, amidofosforanowa (zwykle triamidofosforanowa, ale możliwa jest też diamidofosforanowa i monoamidofosforanowa). Pochodne kwasów karboksylowych mają wiązanie amidowe o strukturze −C(=O)−N<. W białkach wiązanie amidowe nazywane jest peptydowym. (pl)

There is also a neutral amino radical (•NH2) and a positively charged NH2+ ion called a nitrenium ion, but both of these are very unstable. (en)
