RBCs contain hemoglobin (say: HEE-muh-glow-bin), a protein that carries oxygen. (kidshealth.org)
Blood gets its bright red color when hemoglobin picks up oxygen in the lungs . (kidshealth.org)
As the blood travels through the body, the hemoglobin releases oxygen to the different body parts. (kidshealth.org)
This interesting phenomenon occurs when a hemoglobin molecule (the molecule that allows our red blood cells to transport oxygen around our bodies) incorporates a sulphur atom into its structure and becomes sulfhemoglobin. (mcgill.ca)
Hemoglobin contains an atom of iron to bind to oxygen. (mcgill.ca)
This is caused by the tissues on the periphery of their bodies, like the fingertips, not receiving enough oxygen (since sulfhaemoglobin can't transport oxygen like hemoglobin can). (mcgill.ca)
Hemoglobin functions in transporting both oxygen and carbon dioxide and in regulating blood pressure. (proprofs.com)
Hemoglobin is a protein found in red blood cells that plays a crucial role in transporting oxygen from the lungs to the body's tissues and carrying carbon dioxide, a waste product, from the tissues back to the lungs. (proprofs.com)
Additionally, hemoglobin is involved in regulating blood pressure by binding to nitric oxide, a molecule that helps dilate blood vessels and improve blood flow. (proprofs.com)
Hence, most of the products that are in advanced-phase clinical trials are derivatives of hemoglobin and are known as hemoglobin-based oxygen carriers (HBOCs). (medscape.com)
One gram of adult hemoglobin binds to 1.39 milliliters of oxygen. (medscape.com)
The oxyhemoglobin dissociation curve (see the image below) has a characteristic sigmoid shape due to the cooperative effect that exists between the multiple oxygen binding sites on the hemoglobin molecule. (medscape.com)
