Hemoglobin, iron-containing protein in the blood of many animals 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.

Hemoglobin (haemoglobin, Hb or Hgb) is a protein containing iron that facilitates the transport of oxygen in red blood cells. Almost all vertebrates contain hemoglobin, with the exception of the fish family Channichthyidae.
The meaning of HEMOGLOBIN is an iron-containing respiratory pigment of vertebrate red blood cells that consists of a globin composed of four subunits each of which is linked to a heme molecule, that functions in oxygen transport to the tissues after conversion to oxygenated form in the gills or lungs, and that assists in carbon dioxide ...
7 mar 2024 · Hemoglobin (abbreviated Hgb or Hb) is the protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs. Hgb is made up of four protein molecules (globulin chains) that are connected.
Hemoglobin is a polyfunctional molecule that is involved in several functions, such as catalytic (nitrite reductase, NO dioxygenase, monooxygenase, alkylhydroperoxidase, esterase, lipoxygenase); nitric oxide metabolism; metabolic reprogramming; pH regulation and maintaining redox balance ( Kosmachevskaya and Topunov 2018 ).

4 mag 2023 · Hemoglobin is an iron-containing protein in red blood cells (RBCs) that gives blood its red color. It has two primary functions: It transfers oxygen from your lungs to tissues throughout your body, and it carries carbon dioxide from cells back to the lungs so it can be expelled. When hemoglobin is too low, it can indicate certain types of anemia.
