Carbon is the Backbone of Life

All life is built on carbon

Forms large, complex, varied molecules

25% of cells are carbon compounds
Organic Chemistry:

Organic (carbon) compounds
o Form polymers
o Four types
o Carbon can bond with four other atoms
o Forms complex molecules

Organic vs. inorganic molecules
o Organic:
o Inorganic:

Carbon skeletons
o Electron configuration
o Four valence electrons
o Forms single, double, triple, or quadruple bonds
o Four stable covalent bonds (tetravalence)
o Common partners = O, H, N
o Hydrocarbons

Covalent bonding, nonpolar

Store lots of energy – why?

Examples:
o Isomers

Biological relevance

Types

Structural isomers

Cis-trans (geometric) isomers

Enantiomers
o Structure and function

Directly related – structural differences create functional differences

Thalidomide

Functional groups

Chemically reactive, directly involved in reactions

Result in special chemical properties

Hydrophilic, affect molecule reactivity:

Nonreactive, usually serves as tag on biological molecules:

Example of importance:

Hydroxyl
