Chapter 3 (Macromolecules) Flashcards
(17 cards)
Large, complex organic molecules/ contain carbon
Macromolecules
2 Molecules with identical molecular formula, but different structures and characteristics
Isomer
How many covalent bonds does carbon have?
4
- Can form polar or non polar bonds
- Stable at large range of temperatures
- Can bind to several important functional groups
Carbon Bonds
Groups of atoms with special chemical features that are functionally important/ each type of group exhibits the same properties in all molecules in which it occurs
Functional groups
What do functional groups do?
add properties to hydrocarbons
Carbon and hydrogen/ non polar covalent bonds
Hydrocarbon
3 ways isomers may occur:
- Structural isomer
- Cis-trans isomers (stereoisomer)
- Enantiomer (stereoisomer)
Same atoms, but in different bonding relationships & different structure
Structural isomer
Identical bonding relationships, but different spatial positioning of atoms
Stereoisomer (cis-trans & enatiomer)
Four main classes of organic molecules
- Carbohydrates
- Lipids
- Proteins
- Nucleic Acids
One-part/ made of many atoms and molecules
Monomer
Many parts/ made of monomers
Polymer
Sugars, usually long chains
Carbohydrates
Hydrophobic molecules, not a true polymer
Lipids
Polymers of amino acids
Proteins
Polymers of nucleotides
Nucleic Acids
