Document Summary

Polymer: large molecule composed of several connected subunits. Provides support for chemical evolution by stimulating earth"s condition. Outside surface was analyzed and monomer units were found on the outside. May have been contaminated when entering earth"s surface. Life could have been somewhere down in the ocean (hydrothermal vents) Non-ionized has a carboxyl group with oh group and amino group with nh2. Ionized has a carboxyl group with o- and amino group with nh3. Structural isomers: differ in order which the atoms are attached. Geometric isomers differ in the arrangement of atoms around the double bonds (cis and trans) Optical isomers (stereo) and a mirror image of one another. Summary table 3. 1 protein functions (protein type and role in cell or organism) In figure 3. 6, clearly shows hydrolysis and condensation reactions. Condensation or dehydration synthesis : monomer in, water out. Do not need to study enzyme reactions (section in textbook that is not covered in lecture outline)
