Hemoglobin

Hemoglobin --> haemoglobin

(Science: cell biology, haematology) Four subunit globular oxygen carrying protein of the erythrocytes of vertebrates and some invertebrates.

It is a conjugated protein containing four haem groups and globin. There are two alpha and two beta chains (very similar to myoglobin) in adult humans, the haem moiety (an iron containing substituted porphyrin) is firmly held in a nonpolar crevice in each peptide chain.

there are four globin polypeptide chains, designated alpha, beta, gamma, delta in the adult. Each is composed of several hundred amino acids. a hemoprotein composed of globin and heme that gives red blood cells their characteristic color; function primarily to transport oxygen from the lungs to the body tissues; fish have simpler hemoglobin than mammals.


hemoglobin is made up of heme (the iron-containing portion of hemoglobin) and globin (amino acid chains that form a protein). Hemoglobin (Hgb) molecules are found in all red blood cells. They bind oxygen in the lungs, carry the oxygen throughout the body, and release it to the body’s cells and tissues.

Dating of blood stains

... scene. Several publications (listed below) have reported working methods for dating those blood stains. These mainly rely on spectroscopy and the hemoglobin (and other forms) compound. We would like to be initiative and setup some new kind of procedure. We thought about a few things (if you have ...

Re: oxygen "grabbers" haemoglobin adaptation?

To a Chemical Engineer like me (retired) the term "oxygen grabber" can mean chemicals like hemoglobin, or wet iron used to remove atmospheric oxygen in lab work, or even the presence of such materials in the workplace which may pose an industrial hazard (like the ...

Another molecular question

... AAs coded by only one or two codons, you could prepare degenerated probes and use them for the hybridization. However, that will not work for hemoglobin in erythrocytes.

Another molecular question

If you have a cell that is producing a lot of a given protein (such as hemoglobin in erythrocytes) and you want to isolate the gene that transcribes the mRNA for that protein, the method that would likely give you the best results would be I just can't figure ...
