title: [Amino acid composition and affinity to oxygen of domestic duck hemoglobins].
abstract: The method of disk-electrophoresis in PAAG has shown that hemoglobin of domestic ducks is heterogeneous and consists of four electrophoretically homogeneous fractions: two fractions with high content of protein and two minor fractions. They differ in the content of lysine, histidine, serine, glycine, glutamic acid, tyrosine and phenyl alanine as well as in affinity to molecular oxygen. The minor fractions are characterized by low and high affinity to oxygen and fractions with high content of protein occupy an intermediate position.
