Also known as Hb, Hgb, haemoglobins, haemoglobin, hemoglobins

Hemoglobin (haemoglobin, Hb or Hgb) is a protein containing iron that facilitates the transportation of oxygen in red blood cells. Almost all vertebrates contain hemoglobin, with the sole exception of the fish family Channichthyidae. Hemoglobin in the blood carries oxygen from the respiratory organs (lungs or gills) to the other tissues of the body, where it releases the oxygen to enable aerobic respiration which powers an animal's metabolism. A healthy human has 12to 20grams of hemoglobin in every 100mL of blood. Hemoglobin is a metalloprotein, a chromoprotein, and a globulin.

AI overview

Hemoglobin is an iron-containing protein in red blood cells that transports oxygen from your lungs to the rest of your body, where it delivers that oxygen to power your cells. It's found in nearly all vertebrates and is essential for the aerobic respiration that keeps your metabolism running.
