Jan 11 2012 · If a polysaccharide sample is hydrolyzed completely (which means that it must react for a while) the product is glucose In this experiment you will hydrolyze a sample of sucrose and then test it for the presence of a reducing sugar You will also hydrolyze a sample of starch and then test it for the presence of both a reducing sugar and starch

A long-chain carbohydrate. A form of hydrolysis. 1. What does a linear polysaccharide do? Provides energy storage in the form of starch.
Together with other biomolecules like proteins and nucleotides, polysaccharides are an essential component and exert many activities in the biological system such as cell–cell communication, adhesion, and molecular recognition in the immune system [ 2 ].
Polysaccharides can also be classified based on polyelectrolyte to positively charged polysaccharides (chitosan) and negatively charged polysaccharides (alginate, heparin, hyaluronic acid, and pectin [ 5 ].
Other naturally occurring polysaccharides include pectin, guar gum, amylose, inulin, dextran, chitosan, and chondroitin sulphate, which have been investigated for colon-specific drug release and their ability to be used as pharmaceutical excipients [ 65 ].
