Summary Introduction

To review:

The level of protein organization of hemoglobin protein if it is a tetramer of two alpha and two beta-chains.

Introduction:

Protein molecules are made up of amino acid as the monomer units. The kind of amino acids that form a polypeptide chain determine the charge of the protein thus formed and also its shape. This is because amino acid residues help in protein folding by the formation of bonds such hydrogen bonds and disulfide bridges. Protein folding is important for the protein to carry out its function. A misfolded protein is rendered useless. Hemoglobin is a protein of the red blood cells that carries oxygen to different tissues of the body.
