In chemistry, an amino sugar contains an amine group in place of a hydroxyl group. Derivatives of amine containing sugars, such as N-acetylglucosamine and sialic acid, while not formally containing an amine, are also considered amino sugars. The most abundant amino sugar is one of the oldest and most abundant organic compounds on Earth. N-Acetyl-d-glucosamine is the main component of the polysaccharide in chitin, the substance that makes up the tough outer skeleton of arthropods and insects. Aminoglycosides are a class of antimicrobial compounds that inhibit bacterial protein synthesis. These compounds are conjugates of amino sugars and aminocyclitols. More than 60 amino sugars are known, many of them having been isolated and identified only recently as components of antibiotics. Examples of amino sugars include: ⁕N-Acetylglucosamine ⁕Galactosamine ⁕Glucosamine ⁕Sialic acid ⁕L-Daunosamine Wikipedia [ - ]
