  1. Nomenclature Here are just a few of the known polysaccharides and derivatives:

    amylopectinglycogencelluloid
    chitincellulosemucilage
    heparinfructosanagar-agar
    pentosan (hygroscopic)inulinpectin
    xylan (wood, grass)mannosanlignin
    araban (gum)cellophanemuco-
    hexosangun cottonteichoic acid
    glucosan (dextran)pyroxylinmureine
    starchcollodionmucin
    amylosehyaluronic acid 

  2. Structures of several very common polysaccharides

    1. Amylose: poly-glucose-α(1,4)

    2. Amylopectin, Glycogen: poly-glucose-α(1,4) and some α(1,6) (tens of millions of daltons)

    3. Cellulose: poly-glucose-β(1,4) (up to about 2 million daltons)

    4. Chitin: poly-2-acetyl-glucosamine-β(1,4) (up to about 4 million daltons)

    5. Hyaluronic acid: poly-glucuronic acid-β(1,4) (up to about 4 million daltons)

  3. Saccharoids

    1. Ring to open (Haworth to Fisher) as in optical mutarotation catalyzed by acid
      (a lab exercise)

    2. NADH reduction of open ring to poly-alcohol (polyol)

        1α-D-mannopyranoseD-mannitolcough syrup sweetener;
        harmless to teeth
        2α-D-ribofuranoseD-ribitol 
        3α-D-glucopyranoseD-sorbitol 

  4. Chemistry of Sugars

    1. Reducing sugars: the lowest numbered carbon IN THE RING has an -OH; will reduce cupric to cuprous. (a lab exercise)

    2. Periodate oxidation - oxidizes partially oxidized vicinyl carbons both up one step and severs the covalent bond between them. (a lab exercise)

    3. Catabolic Enzymes:

      1. α-amylase (an endoamylase) glucoses
        (a lab exercise)

      2. β-amylase (an exoamylase) maltoses and a "limit" amylose

      3. invertase: sucrose (bad for teeth) glucose + fructose (not bad for teeth AND sweeter)
        (What does the enzyme "invert"?) (a lab exercise)
