oxygen "grabbers" haemoglobin adaptation?

[netsurf]

could someone please help me with this research i need to do:
i require information on how the oxygen grabbers have adapted their haemoglobin to their environment. this covers for example the lama.
links to sources are idea but any information you can give like better search terms would be greatly appreciated

[oscar91]

what are oxygen grabbers?
How do they work?

[kiekyon]

me, too has no idea on what is oxygen 'grabber' hemoglobin

but i do know that llamas live in area of high altitude. i think it is in the andes or himalaya

because of this the oxygen concentration is low. hence they have to have more red blood cells per unit in their blood. also their hemoglobin has higher affinity for oxygen

hope this helps

What I can tell you is that human hemoglobin proteins are made of 4 heme units each containing an iron atom that is necessary to oxygen grabbing. Perhars you should compare human and lama hemoglobin proteins to find out if they have different properties, just like that guy said before, high altitudes are poor in O2 so maybe the lama has more red blood cell wich makes respiration more efficient or it has different hemoglobin proteins.

Maybe the llama haemoglobine resembles the haemoglobine of human fetus? Which has a higher affinity for O2... It has 2 alpha and two gamma chains instead of 2 alpha and 2 beta

Grabbers are the type of animals/organisms in low [O2] enviroment. Such as Llamas at high altitudes. If you look at the oxygen association of curve comparing the human, the llama ones shifts to the left. As they readily need oxygen as their have a high affinity of O2. Compared to lugworm who need O2 but their can wait and consume until the next tide.
