WebMar 10, 2024 · Hemoglobin, a protein, is made up of four amino acid chains. Each of these chains contains heme. Heme is a compound that contains iron. One of the key functions of heme is to transport oxygen in the bloodstream. Hemoglobin is what gives RBCs their shape. RBCs usually look like donuts, but with a thin center instead of a hole. Webhemoglobin, also spelled haemoglobin, iron-containing protein in the blood of many animals—in the red blood cells (erythrocytes) of vertebrates—that transports oxygen to the tissues. Hemoglobin forms an unstable reversible bond with oxygen. In the oxygenated state, it is called oxyhemoglobin and is bright red; in the reduced state, it is purplish blue. … dr k cosmetics
