一、血红蛋白α和β(H b-α和H b-β)的结构和功能人们对血浆中血红蛋白的结构和功能研究已经比较深入,但对血清中游离血红蛋白单链的产生和功能研究却较少。人体血浆中正常的血红蛋白是由一对α链和一对非α链组成的四聚体。α链由141个氨基酸残基构成,含较多组氨酸。非α链有 First, the structure and function of hemoglobin α and β (H b-α and H b-β) The structure and function of hemoglobin in plasma has been more in-depth, but the study of the production and function of free hemoglobin single chain in serum less. Normal hemoglobin in human plasma is a tetramer composed of a pair of alpha chains and a pair of non-alpha chains. The α chain consists of 141 amino acid residues and contains more histidine. Non-alpha chain with
