Hemoglobin - Wikipedia

WebHemoglobin is a globular protein made up of four subunits, each with a heme group. One oxygen molecule is carried by each heme group. The heme groups are linked to one another by a weak ionic connection. The four subunits are linked together by salt bridges and hydrogen bonds in a tetrahedral configuration. The Function of pH WebSummary. Haemoglobin is found in red blood cells and carries oxygen efficiently from the lungs to the tissues in body. It also aids in transporting hydrogen ions and carbon dioxide back to the lungs. Haemoglobin is capable of binding to oxygen (O 2) and gaseous nitric oxide (NO).
