hemoglobin structure
|
4 globin chains - 2 pairs
1 alpha, 1 non-alpha one heme group binds to each globin chain one iron ion per heme |
|
|
different types of hemaglobin
|
A - 2 alpha, 2 beta. 95% of hemoglobin
A2 - 2 alpha, 2 delta. Can't carry oxygen F - 2 alpha, 2 gamma. major hgb of fetal life. Increased oxygen affinity |
|
|
what do you know about the oxygen dissociation curve?
what does left shift and right shift mean? |
puts pO2 against %sat as a measure of oxygen affinity
left shift means that lower partial pressures are needed for oxygen saturation of hgb (higher oxygen affinity) right shift means that higher partial pressures are need for oxygen saturation of hgb (lower oxygen affinity) |
