Study Notes
Hydrocarbon Differences
- Hydrocarbons can differ in structure, including length and branching.
- Variations include hydrocarbons with double bonds and those with ring structures.
Carbon and Hydrogen Bonds
- A carbon atom can form up to four covalent bonds.
- Three hydrogen atoms can be attached to one carbon (carbon a), while only one hydrogen atom can attach to another (carbon b).
Medical Applications
- L-dopa is utilized in the treatment of Parkinson's disease.
- R-dopa has no therapeutic effect on Parkinson's disease.
Isomer Types
- Molecules can be classified as structural isomers, geometric isomers, and enantiomers.
- Structural isomers differ in covalent bond relationships among atoms.
- Geometric isomers differ in atom arrangement around a double bond.
- Enantiomers are mirror images of one another.
Molecular Relationships
- Molecules with different molecular formulas are not considered isomers.
Functional Groups
- Amino groups, phosphate groups, hydroxyl groups, carboxyl groups are examples of functional groups with specific characteristics:
- Hydroxyl groups are typical in alcohols and exhibit high polarity, potentially acting as weak acids.
- Amino groups behave as bases, often picking up hydrogen ions due to nitrogen's electronegativity.
- Thiols are characterized by sulfhydryl groups and can form disulfide bonds.
- Carboxyl groups can act as acids by donating hydrogen ions.
Energy Transfer and Structural Components
- Phosphate groups play a crucial role in energy transfer within ATP.
- Carbonyl groups are distinctive in ketones, with a carbonyl group located in the middle of the carbon skeleton.
Chemical Definitions and Properties
- Tetravalent refers to the ability of carbon to form four bonds.
- Aldehydes can exist as structural isomers of ketones.
- Organic phosphates contribute a negative charge in biochemical reactions.
- Carboxylic acids function as acids due to their ability to donate hydrogen ions.
