Glucinum
(Glu*ci"num) n. [Cf. F. glucinium, glycium, fr. Gr. sweet. Cf. Glycerin.] (Chem.) A rare
metallic element, of a silver white color, and low specific gravity resembling magnesium. It never occurs
naturally in the free state, but is always combined, usually with silica or alumina, or both; as in the minerals
phenacite, chrysoberyl, beryl or emerald, euclase, and danalite. It was named from its oxide glucina,
which was known long before the element was isolated. Symbol Gl. Atomic weight 9.1. Called also
beryllium. [Formerly written also glucinium.]
Glucogen
(Glu"co*gen) n. [R.] See Glycogen.
Glucogenesis
(Glu`co*gen"e*sis) n. Glycogenesis. [R.]
Gluconic
(Glu*con"ic) a. Pertaining to, or derived from, glucose.
Gluconic acid (Chem.), an organic acid, obtained as a colorless, sirupy liquid, by the oxidation of
glucose; — called also maltonic acid, and dextronic acid.
Glucose
(Glu"cose`) n. [Gr. sweet. Cf. Glycerin.]
1. A variety of sugar occurring in nature very abundantly, as in ripe grapes, and in honey, and produced
in great quantities from starch, etc., by the action of heat and acids. It is only about half as sweet as
cane sugar. Called also dextrose, grape sugar, diabetic sugar, and starch sugar. See Dextrose.
2. (Chem.) Any one of a large class of sugars, isometric with glucose proper, and including levulose,
galactose, etc.
3. The trade name of a sirup, obtained as an uncrystallizable reside in the manufacture of glucose proper,
and containing, in addition to some dextrose or glucose, also maltose, dextrin, etc. It is used as a cheap
adulterant of sirups, beers, etc.
Glucoside
(Glu"co*side) n. [See Glucose.] (Chem.) One of a large series of amorphous or crystalline
substances, occurring very widely distributed in plants, rarely in animals, and regarded as influental
agents in the formation and disposition of the sugars. They are frequently of a bitter taste, but, by the
action of ferments, or of dilute acids and alkalies, always break down into some characteristic substance
(acid, aldehyde, alcohol, phenole, or alkaloid) and glucose (or some other sugar); hence the name. They
are of the nature of complex and compound ethers, and ethereal salts of the sugar carbohydrates.
Glucosuria
(||Glu`co*su"ri*a) n. [NL., fr. E. glucose + Gr. urine.] (Med.) A condition in which glucose
is discharged in the urine; diabetes mellitus.
Glue
(Glue) n. [F. glu, L. glus, akin to gluten, from gluere to draw together. Cf. Gluten.] A hard
brittle brownish gelatin, obtained by boiling to a jelly the skins, hoofs, etc., of animals. When gently heated
with water, it becomes viscid and tenaceous, and is used as a cement for uniting substances. The name
is also given to other adhesive or viscous substances.
Bee glue. See under Bee. — Fish glue, a strong kind of glue obtained from fish skins and bladders; isinglass.
— Glue plant (Bot.), a fucoid seaweed (Gloiopeltis tenax). — Liquid glue, a fluid preparation of
glue and acetic acid or alcohol. — Marine glue, a solution of caoutchouc in naphtha, with shellac,
used in shipbuilding.
Glue
(Glue), v. t. [imp. & p. p. Glued ; p. pr. & vb. n. Gluing.] [F. gluer. See Glue, n.] To join

This cold, congealed blood
That glues my lips, and will not let me speak. Shak. Gluepot
(Glue"pot`) n. A utensil for melting glue, consisting of an inner pot holding the glue, immersed
in an outer one containing water which is heated to soften the glue.
