Herpetomonas samuelpessoai polysaccharides

A number of plant [106, 178-183] and algal [64, 176] polysaccharides have structures based on a P(l-4)mannan main chain - P(l-4)mannan, a(l-6)galacto-P(l-4)-D-mannan and the related P(l-4)-D-glucomannan and galacto-P(l-4)glucomannan. They serve as cell wall structural material and as carbohydrate reserve polymers. An unbranched P(l-2) mannan of low molecular weight has been reported from the insect flagellate Herpetomonas samuelpessoai [184].
