Editing Glucose (section)

===Structure and nomenclature===
Glucose is present in solid form as a [[monohydrate]] with a closed [[pyran]] ring (α-D-glucopyranose monohydrate, sometimes known less precisely by dextrose hydrate). In aqueous solution, on the other hand, a small proportion of glucose can be found in an open-chain configuration while remaining predominantly as α- or β-[[pyranose]], which interconvert. From aqueous solutions, the three known forms can be crystallized: α-glucopyranose, β-glucopyranose and α-glucopyranose monohydrate.<ref name="Ullmann">{{Cite book |doi=10.1002/14356007.a12_457.pub2 |chapter=Glucose and Glucose-Containing Syrups |title=Ullmann's Encyclopedia of Industrial Chemistry |year=2006 |last1=Schenck |first1=Fred W. |publisher=Wiley |isbn=978-3-527-30673-2}}</ref> Glucose is a building block of the disaccharides lactose and sucrose (cane or beet sugar), of [[oligosaccharide]]s such as [[raffinose]] and of [[polysaccharide]]s such as [[starch]], [[amylopectin]], [[glycogen]], and [[cellulose]].<ref name="r2"/><ref name="pf"/> The [[glass transition temperature]] of glucose is {{cvt|31|C}} and the Gordon–Taylor constant (an experimentally determined constant for the prediction of the glass transition temperature for different mass fractions of a mixture of two substances)<ref name="pf">Patrick F.
