Amino sugar sulfate ester

Sugars in which a hydroxyl group has been replaced by an amino group are called amino sugars. The amino groups in these compormds are invariably acetylated. When hydroyxl groups are replaced by phosphate or sulfate groups they are known as phosphate and sulfate esters, respectively. [Pg.70]

Variants of keratan sulfate in which other neutral sugars occur and in which there is more than 1 mole of sulfate ester per disaccharide repeating unit are known. Keratan sulfate has also been found to contain smaller amounts of neutral monosaccharides, such as D-mannose and L-fucose, and 5-amino-3,5-dideoxy-D-gZj/cero-D-gcZacto-2-nonulosonic acid. [Pg.13]

Sulfate esters of the amino sugars are widely distributed in nature in heparin, mucoitin sulfate and chondroitin sulfate. The interpretation of the structure of these compounds is difficult, but it may certainly be facilitated since the synthetic sulfate derivatives of the amino sugars permit the study of the alkali and acid stability . ... [Pg.104]
