Study Notes
Hydrocarbons
- Contain only carbon and hydrogen
- Heteroatoms: C and H in organic compounds
- Functional groups: C combines with other atoms to form characteristics structural units
Functional Groups
- Alkanes (saturated hydrocarbons)
- Cycloalkanes (saturated cyclic hydrocarbons)
- Isomers: possible in substituted cycloalkanes (same order, different 3D structure)
- Stereoisomers: atoms connected in the same order but differ in three dimensional orientation
- Stereochemistry: used to refer to the three-dimensional aspects.
- Alkene: carbon-carbon double bond (called olefin)
- Alkyne: carbon-carbon triple bond
- Organohalides: contain one or more halogen atoms
- Aromatic: six-membered benzene rings with three double bonds
- Arenes: alkyl substituted benzenes
- Thiols: sulfur analogs of alcohols (called mercaptans)
- Sulfides: sulfur analogs of ethers
- Aldehydes: changing the terminal -e to -al
- Ketones: changing the terminal -e to -one
Carboxylic Acids, Nitriles, Amines
- Carboxylic acids: RCOâ‚‚H. Occupy a central place among carbonyl compounds
- Nitriles: compounds containing -C≡N
- Amines: organic derivatives of ammonia, heterocyclic amines contain nitrogen in a ring
Carbohydrates
- Broad class of polyhydroxylated aldehydes and ketones; often called sugars
Amino Acids
- Difunctional (basic amino group and acidic carboxyl group)
Lipids
- Naturally occurring organic molecules
Metabolism
- Reactions in cells of living organisms
- Catabolism: breaking down larger molecules into smaller ones
- Anabolism: synthesizing larger molecules from smaller ones
