Study Notes
Carbon
- Central component of organic matter
- Has 4 valence electrons
- Forms 4 covalent bonds
- Carbon-to-carbon bonds are strong, single, double, or triple
Hydrocarbons
- Only contain hydrogen and carbon
Isomers
- Same molecular formula, different structural formula
- Have different physical and chemical properties
- Cells can differentiate between them
Structural Isomers
- Differ in covalent arrangements of atoms
Geometric Isomers
- Same covalent bonds, different spatial arrangement
- Cis: same side
- Trans: opposite sides
Enantiomers
- Mirror images
- Non-superimposable
Organic Compounds
- Contain carbon and hydrogen
- Carbohydrates
- Lipids
- Proteins
- Nucleic acids
Inorganic Compounds
- Do not contain carbon and hydrogen simultaneously
- CO₂
- CaCO₃
Association of Carbon with Other Elements
- Association with oxygen, nitrogen, and phosphorus
- Alters properties
Geometric Isomers
- Cis: groups on the same side of the double bond
- Trans: groups on opposite sides of the double bond
Enantiomers
- Non-superimposable mirror images
Functional Groups and Properties
- Influence an organic molecule's properties
- Hydroxyl
- Carboxyl
- Amino
- Phosphate
- Sulfhydryl
Variety Among Molecules
- Variety influenced by combinations of atoms and functional groups
Hydrocarbons
- Non-polar and hydrophobic
- Insoluble in water
Addition of Hydroxyl Groups
- Polar and hydrophilic
- Soluble in water
Addition of Carbonyl Group
- Aldehyde: carbonyl group at the end of the molecule
- Ketone: carbonyl group in the middle of the molecule
Addition of Carboxyl Group
- Weakly acidic, polar, hydrophilic
- Examples include amino acids
Addition of Amino Group
- Creates a basic group
- Weakly basic
Phosphate Groups
- Non-ionized: R - O - P - OH
- Ionized: R - O - P = O
- Weakly acidic
- Example: Phosphoric ester
Sulfhydryl Groups
- Non-ionized: R - S - H
- Help stabilize proteins
- Example: Cysteine
Biological Molecules
- Many are polymers
- Macromolecules are large
- Polymers make up macromolecules
| Monomer | Polymer |
|---|---|
| Amino acid | protein |
| Monosaccharide | Polysaccharide, Cellulose, Starch, Glycogen |
| Nucleotide | Nucleic acid (RNA and DNA) |
| Fatty acid | Triglyceride |
Polymerization
- Monomers combine to form polymers
