单词 glucose
释义

glucosen.

Brit. /ˈɡluːkəʊz/, /ˈɡluːkəʊs/, U.S. /ˈɡluˌkoʊs/, /ˈɡluˌkoʊz/
Origin: A borrowing from French. Etymon: French glucose.
Etymology: < French glucose a white crystalline sugar of the hexose class (J. Dumas 1838, in Comptes rendus hebd. de l'Acad. des Sci. 7 109), a syrup containing this (1850 in the passage translated in quot. 1852 at sense 2) < ancient Greek γλεῦκος must, sweet wine, sweetness ( < an ablaut variant of the base of γλυκύς sweet: see glyco- comb. form), with u representing ευ and -ose representing -ος : see further discussion at -ose suffix2. Compare glycose n.Compare German Glucose, (now usually) Glukose (1842 or earlier).
1. Chemistry.
a. A white crystalline sugar which is the commonest sugar in nature and a major energy source in living organisms; spec. one of two enantiomers of this, the dextrorotatory (+) form with the d configuration (also d-glucose; = dextrose n.).A monosaccharide, glucose occurs in uncombined form in fruit juices and in blood and cellular fluids, and in combination in polysaccharides (e.g. cellulose, starch, glycogen), oligosaccharides (e.g. sucrose), and glycosides. The laevorotatory (−) enantiomer, l-glucose, is rare in nature and cannot be used as a source of energy by most living organisms.Formula: C6H12O6.
