Respuesta :
Hemoglobin describes the quaternary structure of a protein better.
The complete stable structure of proteins has 4 different levels which are the primary structure, secondary structure, tertiary structure, and quaternary structure. The primary structure is the specific amino acid sequence that is held together by the peptide bonds. The secondary structure is the repeated arrangement of the amino acid backbone. The tertiary structure is the three-dimensional arrangement of the protein structure. Lastly, the quaternary structure is generally the association of different polypeptide bonds in a more complex way.
Hemoglobin has a quaternary structure. It consists of two pairs of different proteins, that are designated the α and β chains. There are 141 and 146 amino acids in the α and β chains of hemoglobin, respectively.
Hence we can say that Hemoglobin describes the quaternary structure of a protein better.
