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

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.
