Why is Haemoglobin often described as the "Robin Hood" Molecule?

Answer 1

Haemoglobin often described as the "Robin Hood" Molecule because its duty resembles with the work of Robin Hood.Pl. read below:

Hemoglobin or haemoglobin (frequently abbreviated as Hb) is the iron-containing oxygen-transport metalloprotein in the red cells of the blood in mammals and other animals. Hemoglobin in vertebrates transports oxygen from the lungs(WHICH IS OXYGEN RICH) to the rest of the body(POOR-IN NEED OF OXYGEN), such as to the muscles, where it releases the oxygen load. Hemoglobin also has a variety of other gas-transport and effect-modulation duties, which vary from species to species, and which in invertebrates may be quite diverse.

The name hemoglobin is the concatenation of heme and globin, reflecting the fact that each subunit of hemoglobin is a globular protein with an embedded heme (or haem) group; each heme group contains an iron atom, and this is responsible for the binding of oxygen. The most common types of hemoglobin contains four such subunits, each with one heme group.

Mutations in the genes for the hemoglobin protein in humans result in a group of hereditary diseases termed the hemoglobinopathies, the most common members of which are sickle-cell disease and thalassemia. Historically in human medicine, hemaglobinopathies were the first diseases to be understood in mechanism of dysfunction, down to the molecular level.

Answer 2

Because it takes from the rich and gives to the poor--hemoglobin acts to transfer oxygen molecules to the body tissues. I takes oxygen from the oxygen rich lungs and delivers it to the comparatively oxygen poor tissue cells throughout the body.

Answer 3

Because it picks up oxygen from lung tissue which is "rich" in oxygen and drops it off at othe tissues which are "poor" in oxygen.

Answer 4

because it's a dirty thieving son of a *****.
