#amino sugar

• Aminose — A generic name given to an amino sugar (or aminose), representing a monosaccharide in whose structure a hydroxyl group (-OH) has been structurally replaced by an amino group (-NH2). The most well-known examples include glucosamine and galactosamine, fundamental compounds that enter the composition of many oligosaccharides, glycoproteins, and essential structural polysaccharides (such as chitin in the exoskeleton of crustaceans or glycosaminoglycans in human cartilage).
• Amino sugar — An organic compound derived from a monosaccharide by the structural replacement of a hydroxyl group (-OH) with an amino group (-NH2). These compounds, also known as aminoses or amino sugars, are fundamental constituents of many structural polysaccharides in nature, such as chitin in the exoskeleton of crustaceans or glycosaminoglycans in human cartilage and connective tissues.
• To aminate — To introduce an amino group or an amine-derived fragment into a monosaccharide or an organic macromolecular structure; a technical or laboratory variant used for the amination process of carbohydrates to form amino sugars. This structural process modifies the polarity and solubility of the target molecule, being applied in biomaterials synthesis.
• To aminate — To introduce an amino group or an amine-derived fragment into the molecular structure of an organic compound, polymer, or carbohydrate; a technical or laboratory variant used equivalently to the amination process. This structural transformation modifies the hydrophilic properties, surface electrical charge, and biochemical reactivity of the target molecule, being applied in biomaterials engineering.
