1945Jrnl. Amer. Chem. Soc. LXVII. 1664/1 In 1901..Von Arlt and Skraup and Kremann showed that chloroform solutions of sugar acetates yielded the acetylated glycosyl chlorides if treated with aluminium chloride and phosphorus pentachloride. 1948W. Pigman Chem. Carbohydrates x. 427 The terms ‘glycosido’ and ‘glycosyl’ have been used as synonyms in much of the older literature. 1956Adv. Enzymol. XVII. 224 There are certain experimental observations inconsistent with the concept of a glycosyl-enzyme complex in individual cases. 1967Cantarow & Schepartz Biochem. (ed. 4) ii. 14 In a newer and less awkward system of nomenclature, the sugar contributing the glycoside linkage is considered to be a sugar radical, the glycosyl radical, formed by removing the hydroxyl from the anomeric carbon. 1988P. W. Kuchel et al. Schaum's Outl. Theory & Probl. Biochem. ii. 44 Maltose and cellobiose are written as shown to indicate clearly..whether the glycosidic bond is α or β with respect to the glycosyl component. |
