1. The functional behaviour of both purified and intracellular trout hemoglobin has been investigated in the presence and absence of adrenaline and at different pHs. 2. A marked difference has been observed in the autoxidation of the two major components of this hemoglobin, Hb-I and Hb-IV, directly related to the different pH dependence of their oxygen affinity. 3. The observed results can be related with an assessment of the different role of the two components under anemia.

Abstract
1. The functional behaviour of both purified and intracellular trout hemoglobin has been investigated in the presence and absence of adrenaline and at different pHs. 2. A marked difference has been observed in the autoxidation of the two major components of this hemoglobin, Hb-I and Hb-IV, directly related to the different pH dependence of their oxygen affinity. 3. The observed results can be related with an assessment of the different role of the two components under anemia.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
