    Study Notes

    Major Functions of Proteins

    • Structure

      • Provides support for tissues and connects various body parts.
      • Examples include collagen and keratin, essential for skin and hair structure.

    • Signaling

      • Functions as chemical messengers that facilitate communication between cells.
      • Important components include membrane proteins, serotonin (linked to mood), and hormones like insulin.

    • Defense

      • Proteins that recognize and bind to foreign materials, playing a key role in the immune response.
      • Immunoglobulins (antibodies) and various cell membrane proteins are critical in this function.

    • Transport

      • Binds to specific substances, enabling their movement throughout the body.
      • Hemoglobin is a primary example, transporting oxygen in the bloodstream alongside membrane transport proteins.

    • Contractile

      • Proteins that allow for muscle contraction and movement by interacting with muscle fibers.
      • Key proteins involved include actin and myosin.

    • Storage

      • Acts to preserve amino acids until the body requires them, ensuring a reserve is available for various functions.
      • Albumin found in egg whites is a notable example of a storage protein.

    • Enzyme

      • Catalyzes specific chemical reactions, significantly increasing their reaction rates.
      • Lactase is a well-known enzyme that breaks down lactose, facilitating dairy digestion.
