Biology Lecture 4 Carbon is the atom of which the structure of life is based. Most organic compounds contain hydrogen in addition to carbon Electron configuration is a key to carbon’s characteristics Valence is the number of bonds that the atom or element wants to form Carbon is replaced by functional groups which show how the cell behaves Hydrocarbons are organic molecules that consist of only carbon and hydrogen Major component of fossil fuels There is a lot of energy in these hydrogen-carbon bonds (source of fuel) When these bonds are broken, the energy in the bonds release energy Isomers are compounds with the same molecular formula (same number of atoms within the molecule). They can look different though and act differently. Structural isomers- differ in covalent partnerships Geometric isomers- same covalent arrangements Enantiomers- molecules that are mirror images of each other Geometric Isomers Cis isomer- x’s are on same sides Trans isomer- x’s are on opposite sides Enantiomers- also called stereo isomers
