Glucose anhydride

Nitration of cellulose may result in the addition of from one to three nitrate groups per glucose anhydride unit. The following compounds and their nitrogen content have been postulated ... 

Analysis of pure cellulose indicates an empirical formula CgHigOj corresponding to a glucose anhydride. There is ample evidence to indicate that in fact cellulose is a high molecular weight polyanhydroglucose. In particular it may be... 

It is to be noticed that although the anhydro ring of levoglucosan is stable to alkali (Tanret s preparative method consisted in the heating of aromatic jS-D-glucosides with aqueous alkali), it readily undergoes scission in the presence of acid. An isomeric glucose anhydride prepared in 1912 by E. Fischer showed, however, very different properties. 

Cellulose, the chief constituent of all living plants, is composed of d-glucose anhydride units, linked by 4 1 /3-o-glucosidic bonds. Chemists...

Cotton. Cotton fibers are comprised mainly of cellulose, a long-chain polymer in which the repeating unit is a glucose anhydride molecule connected by ether links. The polymer has primary and secondary alcohol groups uniformly interspersed throughout the length of the polymer chain. These hydroxyl... 

L. is a glucose anhydride, formed by pyrolysis of - starch or - cellulose. The formation can be considered as the loss of water from glucose with simultaneous intramolecular 1,6-linking 1. is the main reaction product together with numerous other products of thermal deterioration (not regarded in the formula) ...
