he·mo·glo·bin

 (hē′mə-glō′bĭn)
n.
The protein in the red blood cells of vertebrates that carries oxygen from the lungs to tissues and that consists of four polypeptide subunits, each of which is bound to an iron-containing heme molecule.

[Ultimately short for hematinoglobulin : hematin + globulin.]

he•mo•glo•bin

(ˈhi məˌgloʊ bɪn, ˈhɛm ə-)

n.
a conjugated protein in red blood cells, comprising globin and iron-containing heme, that transports oxygen from the lungs to the tissues of the body.
[1865–70; earlier hematoglobulin. See hemo-, globin]
he`mo•glo′bic, adj.

he·mo·glo·bin

(hē′mə-glō′bĭn)
An iron-containing protein in the blood of many animals that, in vertebrates, carries oxygen from the lungs to the tissues of the body and carries carbon dioxide from the tissues to the lungs. Hemoglobin is contained in the red blood cells of vertebrates and gives these cells their characteristic color. Hemoglobin is also found in many invertebrates, where it circulates freely in the blood. See Note at red blood cell.

hemoglobin

1. An oxygen-carrying pigment found in the red blood cells of vertebrate animals.
2. The iron-rich, oxygen-transporting pigment in red blood cells which gives them their color.

Fetal hemoglobin is produced in the womb and for a short period after birth, at which point blood stem cells switch to adult hemoglobin production.
When patients with SCD undergo this transition, their inherited gene mutation distorts adult hemoglobin, forcing red blood cells to assume a sickled shape.
HbAS) given that the HbA1c derived from the adult hemoglobin (HbA) is sufficiently present.
Since fetal hemoglobin is more apt to ferric state compared to adult hemoglobin (Hb A2), newborn infants have a greater tendency to methemoglobinemia.
In the article the researchers said they are one step closer to developing a feasible cure or long-term treatment options for patients with SCD, which is caused by a single DNA letter change in the gene for adult hemoglobin, the principle protein in red blood cells needed to carry oxygen.
Example 2: Fetal hemoglobin is replaced by adult hemoglobin (1) during the first 6 months of life.
There are approximately 300 hemoglobin molecules in each red blood cell, and each hemoglobin can carry four oxygens--one oxygen attached to each of two alpha chains, and two beta chains in the adult hemoglobin.
HbA makes up approximately 97% of normal adult hemoglobin.
Individuals with HPFH demonstrate that preventing or reversing the switch from fetal to adult hemoglobin would provide efficacious therapy for thalassemia and various other hemoglobinopathies.
Two of the four peptides of the fetal and adult hemoglobin chains are identical, that is, the alpha ([alpha]) chains.
6) Infant s and neonates are more susceptible to the development of methemoglobinemia, because fetal hemoglobin is less resistant to oxidant stresses than adult hemoglobin and the enzymatic pathways for the conversion of metHb back to hemoglobin are somewhat deficient in the neonatal period.
However, people with sickle cell anemia and beta-thalassemia have genetic defects in their adult hemoglobin gene.
