BIOL 1361 1nd Edition Lecture 9 Outline of Last Lecture I. Respiratory PigmentsII. Properties of HbIII. pH SensitivityIV. Significance of pH SensitivityExam 2 Material:I. Visualizing Cell AnatomyII. Electron MicroscopeIII. Characteristic of CellsIV. MacromoleculesV. Functional GroupsOutline of Current Lecture I. Amino II. Eukaryotic Organelles and MacromoleculesIII. Biomolecules: Nucleic AcidsCurrent LectureI. Aminoa. Draw the structureb. Name: amines, amino acidsi. Ex. Glycine (drawing)c. Properties: acts as a based. Sulfhydryli. Name: thiolii. Example: cysteineiii. Properties: can form disulfide bridges1. Disulfide Bridgesa. SH groups on 2 different molecules Or…b. On 2different regions of the same moleculec. Can form disulfide bridges, crosslinking molecules or regions within a moleculeThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.e. Methyli. Draw the structureii. Name: methylated compoundsiii. Example: alanineiv. Properties: reduces reactivity of compounds because they’re nonpolarII. Eukaryotic Organelles and Macromoleculesa. Nucleusi. Red fluorescent molecule targeted to a protein in the chromosomeb. Nuclear Envelopei. 3 Components1. Inner Membrane2. Outer Membrane3. Nuclear Porec. Structure of Nucleusi. Nuclear Envelope1. Double phospholipid bilayerii. Nuclear Pores1. Proteins making up a channel through the nuclear envelopeiii. Chromatin1. “colored stuff” inside the nucleus; DNA + proteins = all the chromosomes in the nucleusiv. Nucleolus1. Dense region within the nucleus where ribosomal RNA is being madeIII. Biomolecules: Nucleic Acidsa. Monomer –
