[Histonet] Reaction between Haemoglobin and acetic acid

[kemlo]

SUMMARY
It is shown by sedimentation velocity measurements that the
presence of undissociated acetic acid favors the dissociation of
hemoglobin in a pH region in which hydrogen ion had previously
been thought to have the dominant effect.

Subject: [Histonet] Reaction between Haemoglobin and acetic acid

Hi all,

I have been asked what is the altered haemoglobin called that results
from the treatment of tissues with acetic acid.
All I could think of was that carbon monoxide reacts with haemoglobin to
form carboxyhemoglobin.

Any ideas?
