Hemoglobin is a soluble protein - found in the cytoplasm of red blood cells as single molecules - which bind oxygen and carry it to the tissues.

hemoglobin A red pigment in red blood cells that can bind with oxygen and is largely responsible for the blood's oxygen-carrying capacity. Hemoglobin is composed of four polypeptide chains, two alpha (a) and two beta (b) chains.

hemoglobin -- protein complex found in the blood of most chordates and the roots of certain legumes. It binds oxgen molecules, and in chordates serves as the means by which the oxygen is supplied to the cells of the body.

Hemoglobin transports NO at the same time it carries oxygen [Link to discussion]. When it unloads oxygen in the tissues, it also unloads NO.

hemoglobin An iron-containing respiratory pigment occurring in vertebrate red blood cells and in blood plasma of many invertebrates; a compound of an iron porphyrin heme and globin proteins.
hemoglobinuria Bloody urine.

hemoglobin: a red pigment that binds oxygen and carbon dioxide molecules and carries them through the bloodstream.
herbivores: animals that eat plants.
heterotrophic: species that acquire food from organic matter.

The hemoglobin molecule is the primary transporter of oxygen. 98.5% of the oxygen is chemically combined with the Hb. Only 1.5% is physically dissolved.

sickle-cell anemia A human disease characterized by hemoglobin molecules in which a Glu is replaced by Val. This creates a "sticky patch" when the hemoglobin is deoxygenated, causing hemoglobin molecules to polymerize and deform the red blood cells.

For some individuals with hemoglobin deficiencies, the defects were traced to mutations in the AATAAA sequence.
Cleavage/polyadenylation signals vary in their efficiency.

Sickle-cell anemia is an abnormality of hemoglobin, the molecule that carries oxygen in our blood.

The disorder is caused by a single base pair change in one of the genes that codes for hemoglobin, the blood protein that carries oxygen.

Bohr effect. When blood pH decreases, the ability of hemoglobin to bind to oxygen decreases. An adaptation to release oxygen in the oxygen starved tissues in capillaries where respiratory carbon dioxide lowers blood pH ...
