title: Bohr Effect: Absence in a Molluscan Hemocyanin.
abstract: The hemocyanin of the keyhole limpet, Diodora aspera, shows no Bohr effect within the pH range 6.88 to 7.84. At 10 degrees C the pressure of half-saturation is 5 mm-Hg of oxygen pressure. A moderately positive interaction occurs among the oxygen-combining sites during oxygenation. The heat of oxygenation is calculated to be approximately -12.6 kcal/mole of oxygen. The pH of normal blood of Diodora is lower than that of many other marine molluscs.
