It is a sirupy, or white crystalline, substance, HO.CH₂.CO₂H, has the properties both of an alcohol and an acid, and is a type of the hydroxy acids; — called also hydroxyacetic acid.

Glycolide
(Gly"co*lide) n. [Glycol + anhydride.] (Chem.) A white amorphous powder, C₄H₄O, obtained by heating and dehydrating glycolic acid. [Written also glycollide.]

Glycoluric
(Gly`co*lu"ric) a. [Glycol + uric.] (Chem.) Pertaining to, derived from, glycol and urea; as, glycoluric acid, which is called also hydantoic acid.

Glycoluril
(Gly`co*lu"ril) n. [Glycolyl + uric.] (Chem.) A white, crystalline, nitrogenous substance, obtained by the reduction of allantoïn.

Glycolyl

Glyconian
(Gly*co"ni*an) a. & n. Glyconic.

Glyconic
(Gly*con"ic) a. [Gr. a kind of verse, so called from its inventor, Glycon.] (Pros.) Consisting of a spondee, a choriamb, and a pyrrhic; — applied to a kind of verse in Greek and Latin poetry. — n. (Pros.) A glyconic verse.

Glyconin
(Gly"co*nin) n. An emulsion of glycerin and the yolk of eggs, used as an ointment, as a vehicle for medicines, etc.

Glycosine
(Gly"co*sine) n. (Chem.) An organic base, C₆H₆N₄, produced artificially as a white, crystalline powder, by the action of ammonia on glyoxal.

Glycosuria
(||Gly`co*su"ri*a) n. (Med.) Same as Glucosuria.

Glycyrrhiza
(||Glyc`yr*rhi"za) n. [L., fr. Gr. sweet + root. Cf. Licorice.]

Glycyrrhizimic
(Glyc`yr*rhi*zim"ic) a. (Chem.) From, or pertaining to, glycyrrhizin; as, glycyrrhizimic acid.

Glycyrrhizin
(Gly*cyr"rhi*zin) n. [Cf. F. glycyrrhizine. See Glycyrrhiza.] (Chem.) A glucoside found in licorice root in monesia bark in the root of the walnut, etc., and extracted as a yellow, amorphous powder, of a bittersweet taste.
