- carbon form bond w/ one or more carbon atoms
- variety of carbon skeltons
- carbon-base molecules = organic molecules
- non-carbon-based = inorganic molecules
- carbon bonds w/ other elements
- organic molecule (hydrocarbon) = only carbon + hydrogen
- Methane = abundant hydrocarbon
- group of atoms that react in predictable way = functional group
- carbon skeleton + fuctional group decide properties of organic molecules
- hydroxly groups are water attracting or hydrophilic
- monomer make up polymers
- polymer = straight chain or branching or chains that fold
- four catergories - large molecules
- carbohydrate, lipids, proteins, and nucleic acid
- monomer added to chain, water released
- called dehydration reaction, remove water
- to break chain, add water
- hydrolysis reaction, water is added
Concept Check
1. A molecule with three carbon skeltons, hydroxyl group in the middle
2. Monomers release water to link into chains of polymers
3. During a process of making a polymer, water is released and this is called a dehydration reaction because water is lost
4. Here are three ways in which 5 carbon atoms can be joined
