Bacteria homopolysaccharides

D-Fructose is the most important ketose and is found in all hving plant tissue. In the form of homopolysaccharides (fructans) it serves as a short-term energy reserve in plants, and similar homopolysaccharides are found in bacteria. 

Molecules with a long main chain (backbone) and a few short side chains are called linearly branched p. The majority of all p. are formed by biosynthesis in green plants or in fungi and bacteria. Some important p. are synthesized by animals, such as - chitin, hyaluronic acids or glycogen. P. can be hydrolized (->hydrolysis). P. that yield only one monomer are called homopolysaccharides if there are two or more different monomers, they are heteropolysaccharides.
