glucic

[Eng., ., glucose ); suff.-ic.] Chem.: Contained in, derived from, or in any manner connected with Glucose (q. v.). glucic-acid, 8. Chem.: C12H22O12. An acid obtained along with saccharumic acid, by boiling cane sugar with dilute sulphuric acid; by boiling glucose with baryta water, the precipitate of the barium salt of saccharumic acid is filtered off, and the glucic acid precipitated by means of basic lead acetate, and the lead salt decomposed by H2S. Glucic acid is a honey like ma easily soluble in alcohol and water; it is decomposed by boiling with water, or with dilute acids into formic, acetic, and apo glucinic acids. When boiled with strong acids it is converted into humic acid; some chemists consider this acid to be identical with levulinic acid (q. v.). glu-çi-na, s. [ Gr.glukus =sweet.] Chem.: Oxide of beryllium (q. v.).
