Myoglobin alpha or beta
WebHaemoglobin has a quaternary structure composed of two alpha and two beta subunits, whereas myoglobin has a tertiary structure. What are the functions of haemoglobin and myoglobin? Haemoglobin functions as an oxygen carrier from the lungs to the entire body, and myoglobin functions as a storer of oxygen in the muscle cells. WebThe structure of normal adult hemoglobin can be described as tetramer composed of four myoglobin molecules. a tetramer composed of two alpha beta dimers. a tetramer composed of two alpha 2 and two beta 2 dimers. a tetramer composed of two alpha 2 and two gamma 2 dimers. None of these accurately describe hemoglobin.

WebWhereas myoglobin exists as a monomer, haemoglobin is a tetramer: each of the four subunits is similar in terms of fold to myoglobin. Haemoglobin is a hetero-tetramer, consisting of two alpha subunits and two beta subunits (a "dimer of dimers"), the alpha subunits (141 residues in human haemoglobin) and beta subunits (146) being homologous.
