Does anyone know the difference between [FONT=&quot]carbaminohaemoglobin and carboxyhaeomglobin[/FONT][FONT=&quot]??? or are they the same thing?

Any help would be much appreciated! =)

"Carbaminohemoglobin (also known as carbhemoglobin and carbohemoglobin) is a compound of hemoglobin and carbon dioxide, which is one of the forms in which carbon dioxide exists in the blood. Binding to carbon dioxide lowers hemogobin's affinity for oxygen when carbaminohemoglobin is formed, via the Bohr Effect. When hemoglobin is not bound to oxygen is has a higher tendency to become carbaminohemoglobin, an effect known as the Haldane Effect." (wikipedia)


"Carboxyhemoglobin (British English: Carboxyhaemoglobin) (COHb) is a stable complex of carbon monoxide and hemoglobin that forms in red blood cells when carbon monoxide is inhaled, and hinders delivery of oxygen to the body. Tobacco smoking (through carbon monoxide inhalation) raises the blood levels of COHb." (wikipedia)

hope it helps

As far as I know, you won't need to know something like that.

We get this from Chem... I mean, my tutoring class. It's worth knowing since CO is poisonous and its effect is totally different from that of CO2.

Well great it's not needed! Well I havn't heard it used in chem before so i'm scratcuing all that from my memory (not that I've actually remembered it yet)

You can check buffer in nature in Pathways CHem by Thickett. That's really really really cool.
