glucic, a. Chem.|ˈgl(j)uːsɪk|
[a. F. glucique, f. Gr. γλυκ-ύς sweet: see -ic.
In this word, as in glucina, glucinum, glucose, etc., terms of chemistry chiefly formed in Fr. in the 19th and the latter part of the 18th c., the Gr. υ is abnormally represented by u, instead of by y. Littré in his Dict. substitutes glyc- for gluc- in these words (cf. also glucina, quot. 1819); but the proposed correction has not found acceptance among either French or English chemists.]
In glucic acid, an acid obtained by the action of alkalis or acids on glucose.
1840Turner's Elem. Chem. (ed. 6) iii. 981 By the formation of glucic acid, 1 eq. of sugar disappears for each eq. of lime, and the molasses then contain glucate of lime. 1859Fownes' Man. Chem. 354 Glucic acid is very soluble and deliquescent, has a sour taste, and acid reaction. |
