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.
