Hemoglobin : \Hem"o*glo"bin\, n. [Hemo- _ globe.] (Physiol.)
The normal coloring matter of the red blood corpuscles of
vertebrate animals. It is composed of hematin and globulin,
and is also called h[ae]matoglobulin. In arterial blood, it
is always combined with oxygen, and is then called
oxyhemoglobin. It crystallizes under different forms from
different animals, and when crystallized, is called
h[ae]matocrystallin. See Blood crystal, under Blood.

Hemoglobin : Hemoglobin: The oxygen-carrying pigment and predominant red blood cells . Hemoglobin forms an unstable, reversible bond with oxygen. In its oxygenated state it is called oxyhemoglobin and
is bright red. In the reduced state it is called deoxyhemoglobin and is purple-blue.
Each hemoglobin molecule is made up of four heme groups surrounding a globin group. Heme contains iron and gives a red color to the molecule. Globin consists of two linked pairs of anemia in
which the red cells become sickle-shaped when oxygen is in short supply.
When red blood cells die, the hemoglobin within them is released and broken up: the iron in hemoglobin is salvaged, transported to the bilirubin that is excreted into the bile which is secreted
into the intestine, where it gives the feces their characteristic yellow-brown color.
