The carbohydrate complex of the Chara algaChara aculeolata Kütz includes an acid polysaccharide similar to the pectin substances of higher plants. It is based on a fragment constructed of α-1→4 bound residues of D-galacturonic acid in the pyranose form. The pectin is characterized by a high homogeneity, a considerable content of D-galacturonic acid, and a low degree of acidification of the carboxy groups.
