Human hemoglobin binds oxygen cooperatively and functions as a tetramer composed of two identical alphabeta heterodimers. While… Expand Samples of human adult hemoglobin (HbA) encapsulated in a wet porous sol-gel are prepared under aerobic and anaerobic conditions… Expand To probe the distortions of the heme groups resulting from heme-apoprotein interaction in the isolated subunits of oxygenated… Expand Bis(3,5-dibromosalicyl) fumarate and a number of related bifunctional reagents react preferentially with oxyhemoglobin to cross… Expand Several hemoglobins and bovine myoglobin are shown to undergo autooxidation reactions promoted by anions. The reduced protein in… Expand It is demonstrated that tracer diffusion coefficients can be determined for oxyhemoglobin A (HbA-O2) and oxyhemoglobin S (HbS-O2… Expand Subpicosecond optical pulses have been used to study the photolysis of hemoglobin conplexes. Photodissociation of… Expand Interaction of acetylphenylhydrazine with oxyhemoglobin A in a hemolysate or in intact red cells resulted in the formation of… Expand
