330 Class Notes Amino Acids and Proteins 2.22.12 Slide 2: Proteins Have Many Biological Functions Enzymes involved in DNA replication, Transcription, transport. Slide 3: Oligomeric State of Macromolecules. Assembling of amino acid Slide 4: General Structure of AA's Slide 5: Ionized Form of Amino Acids Zwitter ion…can act as an acid and base in solution. Slide 6: Acidic Side Chains Negative charges on the oxygen. Slide 7: Basic Side Chains Positive charges on the nitrogen. Slide 8: Uncharged Polar Side Chains Have electronegative atoms, that give them polarity. -NH2 groups where the N and O are very electronegative, and have polarity. Slide 10: Nonpolar Side Chains (Methionine and cysteins in the polar category). Slide 11: Peptide Bond links AA's Two AA's are joined together through a peptide bond through a condensation reaction. Slide 12: Condensation and Hydrolysis Reactions are Important in Biological Reactions Taking hydroxyl and hydrogen and condensing them into water. Present when linking two monomers together.
