| Abstract |
1. In hypoxic conditions Artemia salina L. forms 3 hemoglobins, which until now had only been characterized by their electrophoretic mobility. 2. We have analysed the oxygen-binding properties of these 3 hemoglobins. 3. HbI shows the lowest oxygen affinity, has an almost negligible Bohr effect and it has no physiological adaptation to temperature changes. 4. HbII shows an intermediate oxygen affinity and a pronounced positive Bohr effect. 5. HbIII has a very high affinity for oxygen, an almost negligible Bohr effect and a good physiological adaptation to temperature changes. 6. By combining the 3 hemoglobins in different proportions Artemia salina L. must be able to withstand diverging environmental conditions. |
