Abstract
  • Linus Pauling incorporated hemoglobin and a disease of the blood, sickle cell anemia, into many of his researches between the mid-1930s and mid-1970s. In the early 1930s Pauling became interested in organic chemistry and named hemoglobin as one of the first biochemical substances that he planned to analyze. In 1935 he published his first paper on hemoglobin, which determined the structure of the four hemes in hemoglobin. Pauling continued to study the structure of hemoglobin until the early 1950s when he proposed that it was an alpha-helix. In 1945 Pauling learned about sickle cell anemia and published an important paper in 1949 with Harvey A. Itano, S.J. Singer, and Ibert C. Wells titled "Sickle Cell Anemia, a Molecular Disease." Pauling investigated hemoglobin into the mid-1970s when he tried to find an orthomolecular therapy for sickle cell anemia. From the mid-1950s to early 1970s, Pauling also used sickle cell anemia to promote negative eugenics, point out the possible mutagenic effects caused by nuclear weapons testing, and propose an evolutionary theory. Additionally, in the final year of his life, Pauling wrote two forewords for books on sickle cell anemia, which were published in 1994, the year he died. Hemoglobin and sickle cell anemia can be considered a theme within Pauling's work. He often returned to normal and abnormal hemoglobin as his primary substance for examination, and his familiarity with hemoglobin and sickle cell anemia inspired new research.
