  5. Observed color Absorbed color (nm) (nm)

  6. ColorsofBlood • Result from absorption of visible radiation by hemoglobin: • A protein that contains Fe(II) bonded through d-orbitals to an organic molecule referred to as porphyrin • Occurs when radiation has the quantum energy needed to raise an e-from its ground state to an excited state • Oxygenated blood is bright red  ~ 620 nm; Deoxygenated blood is dark bluish-red

  8. Hemoglobin & Myoglobin proteins that transport and store O2

  9. Fe2+ in Oxymyoglobin and Oxyhemoglobin

  10. Did you ever have a vampire encounter? Is Bram Stoker’s “Dracula” pure fiction? Do vampires have any preference arterial or venous blood? Vampires & Porphyria?Eduard Munch

  11. Porphyria http://en.wikipedia.org/wiki/Porphyria Erythropoietic porphyria symptoms: Severe photosensitivity, swelling, pain, and burning; requires avoidance of bright sunlight; produces brown canine teeth that fluoresce in ultraviolet light; produces hemolytic anemia. Drinking large quantities of blood can alleviate the symptoms. Garlic activates an enzyme that destroys them faster and makes the symptoms of porphyria worse. Q. "Why is a baby like a vampire? A "Because it sleeps all day and feeds all night."

  13. Edvard Munch (1863–1944) SF MOMA July 1-October 5, 2017 Eduard Munch

  14. The woman in the photo discovered and named me in 1898. I have 33 known isotopes. There is about 10 mg of me in every metric ton of uranium. Ingesting ~50 nanograms(5 x10-8g) of me, or inhaling ~1 x 10-8g will most likely cause death. The Russians fed me to Alexander Litvinenko in 2006. My most common isotope has 125 neutrons. I have 84 protons. I am Polonium named by Madame Curie for her native Poland. Trick or Treat: What element am I?
