Glucose
Pronunciation
Definition 1
A type of sugar; the chief source of energy for living organisms. (NCI Dictionary)
Definition 2
A simple sugar monosaccharide having two isoforms, alpha and beta, with a chemical structure of C6H12O6 that acts as an energy source for both plants and animals by reacting with oxygen, generating carbon dioxide and water, and releasing energy. (NCI Thesaurus)
Definition 3
A hexose with an aldehyde group; in which each of the 5 remaining carbons other than the aldehyde group has one hydroxyl group in the R,S,R, and R configuration counting from the first hydroxyl containing carbon next to the aldehyde in the straight chain (Fisher) projection; otherwise all carbons have exclusively hydrogens. Occurs mostly as pyran (6-membered oxygen containing ring or oxane) and rarely as furan (5-membered oxygen containing ring) or straight chain. When glucose forms a ring an additional ""anomeric"" asymmetric carbon is created which is denoted as ""alpha"" or ""beta"". For isomers see http://en.wikipedia.org/wiki/Glucose. (NCI Thesaurus/CRCH)
