Document Summary

Makes overall solution resistant to ph change, because they react with both added acids and bases. Must set up solution in such a way that you start at the half equivalence point. Set up equal moles of solution of the acid and conjugate base. Proteins, nucleic acids, carbohydrates -> form huge polymers. Polymers are made of monomers bound together by covalent bonds -> polymerization. Hydrolysis is opposite; water in, monomer out. Are made the same way in living things and roughly in the same proportion. Organisms can acquire needed biochemicals by eating other organisms. Range from a few amino acids to thousands. Folding is crucial to the function of a protein and is influenced by the sequence of amino acids. Every amino acid has a amino group (n terminus), side r" chain, and. Nonpolar side chains only contain c and h. Electrically charged side chains contain a charge.
