Abstract

Publisher Summary This chapter discusses the chemical properties of a group of substances called acidic mucopolysaccharides. Most of them are present in the connective tissue of animals. Their most characteristic chemical feature is a structure built of alternate units of amino sugar and glycuronic acid, the acidic character being reinforced in some of them by sulfate groups. Proteins coextracted by salt or alkaline solutions can be precipitated with the usual reagents such as phosphotungstic acid, phosphomolybdic acid, picric acid, etc., or denatured with Sevag's reagent, followed by precipitation of the polysaccharide with alcohol. Trichloroacetic acid, phenol, or acetic acid extractions have also been used with success.
