Formation of bonds W/ Carbon
|
Carbon is tetravalent which means that there are 4 unpaired e- in valence shell. Carbon can share 4 e- w/ other atoms (covelent). Thus formation of large complex molecules are possible.
|
|
Molecular diversity arising from carbon skeleton variations are
|
- Hydrocarbons
- Isomers |
|
Hydrocarbons are
|
hyrophobic (non polar covalent bonds between C & H not water soluble.) It is also a major component of petroleum (fossil Fuel). The have a high E potential which means breaking down hydrocarbons releases large amount of E. example is Fat
|
|
Isomers are
(iso means the same) |
same elements configured differently. thier structure indicates thier fuction and they have different properties.
-structural isomers -geometric isomers -enatiomers |
|
structural isomers have
|
Different locations of the atoms and differ in arranngment of double bonds
|
|
Geometric isomers have
|
the same covalent partnerships but different spatial arrangments. the double bonds eliminate rotation.
|
|
enatiomers have
|
a molecules that are mirror images of one another (like your left and right hands) structure = fuction
EX. Thalidomine in the late 50's early 60's reduced morning sickness and later caused birth defects. |
|
fuctional groups are the parts of molecules involved in chemical reactions
|
Fuctional groups
and cellualr respiration |
|
Fuctional groups are most important in the chemistry of life
|
they behave consistantly from molecule to molecule and help to determine the unique properties of molecules. Many are water soluble which is important to tranportation thru blood.
|
|
cellular respiration
|
has Adenosine Triphophate ATP
and an important source of E for cellular work. **** memorize p. 64-65 |
