Is hemoglobin a tertiary structure

WebHemoglobin is a tetramer composed of two each of two types of closely related subunits, alpha and beta. Myoglobin is a monomer (so it doesn't have a quaternary structure at all). Myoglobin binds oxygen more tightly … WebGlobin is the specific part of hemoglobin which varies according to age, species, and in certain diseases. In myoglobins there is a single polypeptide chain (combined with one heme) whose primary, secondary and tertiary structure is known, at least in certain species (see figure 1-19). Molecular weight is about 17 000.
