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.
