In these tissues, hemoglobin has a non-oxygen-carrying function as an antioxidant and a regulator of iron metabolism. Hemoglobin and hemoglobin-like molecules are also found in many invertebrates, fungi, and plants.

Each polypeptide chain is comprised of 141 to 146 amino acids each. The sequence and number of amino acids is determined by structural genes. Variations in amino acid sequence give rise to different types of polypeptide chains.

Hemoglobin is the main protein in mature red blood cells. Each RBC contains over 600 million hemoglobin molecules. It is tetramer, that is, one molecule of hemoglobin in adult is composed of four globin chains, 2 alpha and 2 beta. These chains are derived from chromosome, mainly chromosome 16 and 11. During the various stages of life such as embryonic, fetal and adult stages, different globin chains are expressed.

Blood is a specialized body fluid. It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including: transporting oxygen and nutrients to the lungs and tissues.

Hemoglobin is also found outside red blood cells and their progenitor lines. Other cells that contain hemoglobin include the A9 dopaminergic neurons in the substantia nigra, macrophages, alveolar cells, and mesangial cells in the kidney.

The major role of hemoglobin is to carry oxygen from the lungs to the tissues and return carbon dioxide (CO2) from the tissue to the lungs. It is the oxygen carrying component of RBCs.

Hemoglobin (/ˈhiːməˌɡloʊbᵻn, ˈhɛ-, -moʊ-/); also spelled haemoglobin and abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein in the red blood cells of all vertebrates (with the exception of the fish family Channichthyidae) as well as the tissues of some invertebrates.

How Heme and Globin come together. Once released from the ribosome, each globin chains pairs off with a heme molecule. An alpha globin and non-alpha globin chain then binds forming a heterodimer. 2 heterodimers then combine to form a tetramer hemoglobin molecule (4 chains)

Hemoglobin in the blood carries oxygen from the respiratory organs (lungs or gills) to the rest of the body (i.e. the tissues). There it releases the oxygen to permit aerobic respiration to provide energy to power the functions of the organism in the process called metabolism.

The mammalian hemoglobin molecule can bind (carry) up to four oxygen molecules. Hemoglobin is involved in the transport of other gases: It carries some of the body's respiratory carbon dioxide (about 20–25% of the total) as carbaminohemoglobin, in which CO2 is bound to the globin protein.

what is the function (purpose) of hemoglobin
the function of hemoglobin is to transport oxygen and nutrients to the lungs and tissues. The function of hemoglobin is to transport oxygen and nutrients to the lungs and tissues.
