(2002) reported that genetic line had pH, the heme iron is predominantly in the significant effects on a* value (redness), ferrous state (Fe2+); low pH accelerates which ranged from 9.2 to 11 (on a 15-point ferrous iron conversion to the ferric state scale) among pigs from genetic lines known Table 2.3. Characteristics of various states of myoglobin Pigment Ligand Conditions Iron State Color Deoxymyoglobin H2O Very low oxygen tension Fe++ Purple-red/purple-pink (<5 mm Hg). H2O is ionically (reversibly) bound to Fe++ Oxymyoglobin :O2 High O2 tension (70–80 mm Hg). Fe++ Bright red/bright pink O2 is covalently bound to Fe++ Metmyoglobin — Low O2 tension (∼10 mm Hg). An Fe+++ Brown/grey
