Chem.)</fld> <def>A crystalline, nitrogenous substance, with a sweet taste, formed from hippuric acid by boiling with hydrochloric acid, and present in bile united with cholic acid. It is also formed from gelatin by decomposition with acids. Chemically, it is amido-acetic acid. Called also <altname>glycin</altname>, and <altname>glycocin</altname>.</def>

Chem.)</fld> <def>A white, amorphous, tasteless substance resembling starch, soluble in water to an opalescent fluid. It is found abundantly in the liver of most animals, and in small quantity in other organs and tissues, particularly in the embryo. It is quickly changed into sugar when boiled with dilute sulphuric or hydrochloric acid, and also by the action of amylolytic ferments.</def> <-- polysaccharide, used as a sugar storage substance in animals -->
