Study of the highly oxidizing centers in the metmyoglobin-H2O2 reaction
Metmyoglobin (MbFe III ) from horse heart forms an oxyferryl heme (Fe IV = O) and an unstable protein radical upon reaction with H 2 O 2 . Chemical modifications to the globin and heme have been reported as by-products of the reaction. Damage to the polypeptide was found to be linked to the Fe IV = …

Study of locally unfolded forms of cytochrome c by Fourier transform infrared and of H2O2-mediated oxidation of ferricytochrome c and metmyoglobin by mass spectrometry
The reaction of hydrogen peroxide (H 2 O 2 ) with metmyoglobin (Mb) and ferricytochrome c (cyt c) forms highly reactive intermediates that are believed to be important in myocardial reperfusion injuries and in triggering apoptosis, respectively. Furthermore, the alkaline isomer(s) of cyt c have …

Myoglobin redox form stabilization: role of metabolic intermediates and NIR detection
… 1, we investigated the relationship between metmyoglobin (MMb) reduction and oxidation of malate to α-ketoglutarate with regeneration of reduced nicotinamide adenine dinucleotide (NADH) via malate dehydrogenase (MDH). Our specific objectives for this experiment were: (1) to examine the …

Effects of packaging and soy protein isolate antioxidant on lipid oxidation of ground beef
… increased, TBA value, visual brownness, and metmyoglobin increased while visual redness, acceptability, a* value, red color contributed by oxymyoglobin, and deoxymyoglobin decreased. Location on the meat block (exterior vs interior) affected (p $<$ 0.05) visual red and brown color, color …

Selected skeletal alteration to improve beef tenderness
… values and oxymyoglobin, reduced myoglobin and metmyoglobin values measured on samples at the treatment site. Sensory panel ratings of visual attributes of color and overall appearance were less desirable (P<0.05) for the treated sides, while for visible texture ratings, there was no significant …

Promoting oxygenation of vacuum packaged fresh pork using soybean leghemoglobin
… in oxymyoglobin than low Lb treatments. Metmyoglobin of HLb treatments was higher (P<0.05) than the Vac-pack and the buffer treatments on the day of manufacture. pH did not affect (P>0.05) sensory or objective color, pigment state, purge or total psychrotrophic aerobic bacterial counts …

Aspects of the hemes and modulation of hydrogen donors in catalases from bovine liver, yeast, and escherichia coli
… migrations that are known to occur within metmyoglobin and cytochrome c peroxidase when reacted with H202. Validation of these hypotheses may be obtained in appropriate future experiments.
