    Study Notes

    Chemical Bonds and Equations

    • Chemical bonds form between two hydrogen atoms, creating hydrogen gas (H₂) as a product.
    • Chemical equations symbolize chemical reactions; for example, H + H = H₂ (where H represents reactants and H₂ represents the product).

    Types of Compounds

    • Blood is classified as a suspension.
    • Water (H₂O) is a molecule that serves as a vital medium for biological processes.
    • Hydrogen gas (H₂) is a compound formed from diatomic hydrogen atoms.
    • Sugar dissolved in water exemplifies a solution, where solute and solvent interact.

    Biological Macromolecules

    • Essential biological macromolecules include:
      • Proteins: Complex structures with various functions.
      • Carbohydrates: Energy sources and structural components.
      • Lipids (Fats): Energy storage and membrane formation.
      • Nucleic acids: Genetic information carriers (DNA and RNA).

    Inorganic Compounds

    • Inorganic compounds typically lack carbon and include:
      • Water: Essential for life and biological reactions.
      • Salts: Ionic compounds that can affect physiological processes.
      • Acids: Substances that can donate protons (H⁺ ions) in solutions.
      • High Heat Capacity: Water's ability to absorb significant heat energy, stabilizing temperature changes in environments.

    Protein Structure

    • Tertiary structure involves interactions between the R-groups of distantly positioned amino acids along the polypeptide chain, influencing the overall shape and function of the protein.
