    Study Notes

    Polysaccharides

    • Composed of a large number of monomers
    • Examples include starch, glycogen, and cellulose

    Carbohydrates

    • Primary source of energy storage in the form of starch (plants) and glycogen (animals)

    Microorganisms

    • Ability to grow in food is determined by water activity, pH, temperature, and nutrient availability

    Food

    • Water is the most abundant constituent present in food

    Monosaccharides

    • Act as building blocks in the formation of disaccharides and polysaccharides

    Water Molecules

    • Hydrogen and oxygen atoms form covalent bonds

    Fiber

    • Do not taste sweet and are insoluble in water

    Reducing Sugars

    • Known for their ability to reduce other compounds.
