Glucose (/ˈɡluːkoʊs/ or /-koʊz/; C6H12O6, an aa kent as D-glucose, dextrose, or grape sugar) is a simple monosaccharide foond in plants. It is ane o the three dietary monosaccharides, alang wi fructose an galactose, that are absorbed directly intae the bluidstream durin digestion. An important carbohydrate in biology, cells uise it as the primary soorce o energy[3] an a metabolic intermediate. Glucose is ane o the main products o photosynthesis an fuels for cellular respiration. Glucose exists in several different molecular structures, but aw o these structurs can be dividit intae twa faimilies o mirror-images (stereoisomers). Anly ane set o these isomers exists in naitur, those derived frae the "richt-haundit furm" o glucose, denotit D-glucose. D-glucose is sometimes referred tae as dextrose, altho the uise o this name is strangly discouraged. The term dextrose is derived frae dextrorotatory glucose.[4] This name is tharefore confusin when applied tae the enantiomer, which rotates licht in the opposite direction. Starch an cellulose are polymers derived frae the dehydration o D-glucose. The ither stereoisomer, cried L-glucose, is hairdly ever foond in naitur.
The name "glucose" comes frae the Greek wird glukus (γλυκύς), meanin "sweet". The suffix "-ose" denotes a succar.
