    Study Notes

    Organic and Inorganic Compounds

    • Organic compounds consist of carbon atoms bonded to other carbon atoms.
    • Inorganic compounds generally do not contain carbon, with carbon dioxide being a notable exception.

    Characteristics of Carbon

    • Carbon has four valence electrons, allowing it to form strong and stable covalent bonds.
    • It can create four covalent bonds with other carbon atoms and elements like oxygen, hydrogen, nitrogen, sulfur, and phosphorus.
    • Carbon forms versatile structures, including straight chains, branched chains, or rings.
    • Carbon chains can vary dramatically in length, enabling vast structural diversity in molecules.
    • The self-bonding capability of carbon leads to an extensive variety of organic compounds.
    • The three-dimensional shape of carbon molecules is crucial for their properties and functions in biological systems.
    • Carbon compounds have low solubility in water.
    • Carbon is abundant and widely available in nature.
    • No other element possesses all these characteristics, making carbon unique.

    Functional Groups

    • Functional groups are specific atom clusters attached to carbon "skeletons," influencing molecular shape and reactivity.
    • Each functional group has a distinct role in chemical reactions.
    • Four key functional groups important for living organisms:
      • Hydroxyl (–OH)
      • Carboxyl (–COOH)
      • Amino (–NH₂)
      • Phosphate (–PO₄)

    Macromolecules

    • Macromolecules are large molecules formed by linking smaller ones.
    • Four primary classes of macromolecules: carbohydrates, lipids, proteins, and nucleic acids.
    • Macromolecules are created through polymerization, where small units join to create larger compounds.
    • Monomers are the building blocks that combine to form polymers.
    • Polymers have repetitive structural units connected by covalent bonds; for example, starch is a polymer made from glucose monomers.
    • Macromolecules are continuously synthesized and degraded within living cells via condensation and hydrolysis reactions.

    Condensation Reaction

    • A condensation reaction connects monomers to form polymers, removing a water molecule in the process.
    • One monomer provides a hydroxyl group, while the other supplies a hydrogen atom.
    • Energy expenditure is required to drive condensation reactions.
    • Enzymes facilitate these reactions.

    Hydrolysis

    • Hydrolysis breaks polymers down into monomers, essentially reversing the condensation process.
    • Water is used in hydrolysis to cleave bonds linking monomers.
    • An example of hydrolysis is digestion, where large food polymers are reduced to smaller monomers, which enter cells and can be reassembled into new polymers through condensation.

    Polymers from Monomers

    • A vast array of polymers can be constructed from a limited number of monomers.
    • Approximately 40 to 50 common monomers are used universally by living organisms to form macromolecules.
    • This phenomenon is analogous to creating thousands of words from a limited set of alphabet letters.
