Carbon Compounds
Carbon Bonding Carbon-4 electrons in outer level Can bond with more other atoms than any other element Can bond with itself to form: Straight chains (i.e. butane) Branched chains (i.e. isobutene) Rings Light Organic Compound Any compound that is produced by or part of a living thing Always contains carbon Functional groups 2/+ atoms bonded together that function as a single atom Clusters of atoms Influence properties of molecules they compose Structural building blocks Determine characteristics of compounds i.e. hydroxyl group (_OH) Sugars and alcohols have no charge alcohol organic comp. w/ a hydroxyl group attached to one of its carbon atoms polar properties similar to water b/c of hydrogen bonds ethanol-causes cell death in liver and in brain methanol- causes blindness, death glycerol- necessary to assemble certain molecules (_C=O) Carbonyl group Sugars, lipids(fats and oils) Amino acids (_COOH) Carboxyl Acid (_NH2) Amino base Large carbon molecules Built from smaller, simpler molecules(monomers) Monomers bond to one another and form polymers Monomer-repeating subunit Polymers consist of repeated linked units ?-?-?-?-?-?-?-?-?-?-? string of monomers bonded together Large polymers- macro polymers Monomers link to form polymers through condensation reactions Breakdown of polymers-hydrolysis(reversal of condensation reaction) Adding water to some complex molecules sometimes breaks them down Energy Currency Life processes require constant supply of energy Available in adenosine triphosphate (ATP) Breaking covalent bonds releases energy Dehydration Synthesis(condensation) H-?-OH H-?-OH H-?-?-OH H2O H-?-?-?-?-?-?-?-?-?-?-OH Synthesis-to make Hydrolysis Lysis-to split i.e. digestion the process of splitting water to break polymers into monomers
