WebMay 17, 2016 · Haemoglobin exists in two forms: taut (T), which has a low affinity for oxygen; and relaxed (R), which has a high affinity for oxygen. The taut form predominates in the tissues (a high carbon dioxide, low pH environment) promoting oxygen release, whereas the relaxed form binds oxygen more avidly in areas of high pH, low carbon …
