|
Sucrose |
(Glucose + Fructose) ♢ Most abundant disaccharide , ♢ Obtained commercially from sugar cane , ♢ Most commonly found in plants in the phloem tissue and is transported in large amounts , ♢ Very soluble therefore moved efficiently in high concentrations , ♢ Relatively unreactive chemically and therefore does not enter general metabolism. |
|
|
Lactose |
(Glucose + Galactose) ♢ Major sugar in milk , ♢ Important energy source in young mammals , ♢ Digested slowly and therefore gives a steady release of energy. |
|
|
Maltose |
(Glucose + Glucose) ♢ Product of starch digestion by amalyse emzyme , ♢ Occurs in animals and germinating seeds, ♢ Used in the brewing of beer as the germiating barley is stimulated and results in the conversion of starch to maltose. Maltose fermented by yeast to alcohol. |
|
|
Starch |
(Polysaccharide) ♢ Straight and branched chains of glucose molecules , ♢ Storage molecule in plants , ♢ Principle storage in plants. |
|
|
Glycogen |
(Polysaccharide) ♢ Storage molecule in animals , ♢ Stored chiefly in the liver and muscles of vertebrates , ♢ Provides a useful energy reserve , ♢ Short chains and therfore can be quickly metabolized to release energy. |
|
|
Cellulose |
(Polysaccharide) ♢Structural component of all plant cell walls , ♢ Straight, rigid chains of glucose molecules/residues , ♢ High tensile strength due to the chains forming microfibrils , ♢ Withstand osmotic pressure. |
