Abstract

Abstract The tunic of several Ascidian species, and the body wall of a sea cucumber, contain high amounts of sulfated glycans, at a concentration which is similar to that of sulfated glycosaminoglycans in vertebrate cartilales. The glycans from the different species are distinguished by the pattern of electrophoretic migration and by the molar proportion of amino sugars, hexoses and sulfate. The possibility that these compounds be involved in the maintenance of the integrity of these tissues, resembling the strutural function of the glycosaminoglycans in vertebrate cartilages, is discussed.
