As glucose is a stable molecule, it is impossible for any two OH groups to bind to the same carbon.

Presence of 5 OH groups: Pentadactyl derivatives are formed when glucose reacts with acetic anhydride, indicating five hydroxyl groups.

Presence of a 6-carbon unbranched chain: Glucose has an unbranched six-carbon chain, proven by the fact that it totally reduces when combined with concentrated hydrogen iodide and red phosphorus to produce n-hexane.

Molecular formula: The molecular formula of glucose is C 6H 12O 6 based on the analysis of elements in glucose and the molecular weight of glucose.

Open-chain form: Glucose has a backbone that is not open or branched, and it is made of six carbon atoms in its open-chain form. This results in a ring with six members, i.e., five carbons and one oxygen. The -OH on carbon number 5 converts to the ether linkage to seal the ring with carbon number 1 due to the tetrahedral geometry of carbons that eventually form a 6-membered stable ring. Glucose is made of six carbon atoms, 12 hydrogen atoms, and six oxygen atoms. Another important glucose-based molecule is cellulose.

The principal energy-reserve carbohydrate in plants, starch, is made of thousands of linear glucose units. It powers cell function, and its metabolism must be carefully regulated.

Found in fruits and honey, it is the most common free sugar in higher animals’ blood. It is commonly known as dextrose and belongs to the group of carbohydrates known as simple sugars (monosaccharides). Available fields are: Gene name ( HGNC name or synonyms), Protein class, Chromosome, External identifier ( Ensembl gene, transcript or protein identifier, UniProt accession number, NCBI Entrez gene identifier), Subcellular location based on immunofluorescent staining in three different cell lines, Organ-, Tissue-, Cancer- and Cell line expression, Antibody validation results in four different assays ( IH=immunohistochemistry, IF=immunoflourescence, WB=Western blot, PA=Protein array), evidence scores and a filtration on Genes with antibodies only and Genes with knowledge-based annotated protein expression ( IH, IF).Glucose gets its name from the Greek word glykys, which means sweet.

Specific fields can be searched by using the "Fields"-function. The free text query word needs to be at least three characters long. The free text search will scan for complete and partial matches to gene names, gene synonyms, gene descriptions, external ( UniProt, Ensembl, NCBI Entrez Gene) gene and protein identifiers, protein classes, Gene Ontology identifiers and descriptions, antibody identifiers and image annotations. The search function can be used for free text search (type anything in the search field), or for more complex queries using "Fields" (see examples).
