Nitrite is one of the players in the broad nitrogen biogeochemical cycle. This nitrogen oxo-
anion is involved in key pathways crucial to life on Earth and to the planetary “recycling” of …

The heme in the active center of peroxidases reacts with hydrogen peroxide to form highly
reactive intermediates, which then oxidize simple substances called peroxidase substrates …

The effects of the retail display temperature (8° C, 3° C and− 1° C) on the discoloration of the
Longissimus thoracis et lumborum of rabbits and the associations among such effects with …

Oxygen transport, oxygen storage and oxygen activation in aerobic organisms depend on
the iron porphyrin moiety in heme proteins. Under fluctuating oxygen supply and pH …

Pentacoordinate respiratory hemoproteins such as hemoglobin and myoglobin have
evolved to supply cells with oxygen. However, these respiratory heme proteins are also …

Hemoproteins, hemoglobin and myoglobin, once released from cells can cause severe
oxidative damage as a consequence of heme redox cycling between ferric and ferryl states …

Recent research has shown that myoglobin and hemoglobin play important roles in the
pathology of certain disease states, such as renal dysfunction following rhabdomyolysis and …

Rhabdomyolysis-induced renal failure represents up to 15% of all cases of acute renal
failure. Many studies over the past 4 decades have demonstrated that accumulation of …

Hydrogen peroxide (H 2 O 2) triggers a redox cycle between ferric and ferryl hemoglobin
(Hb) leading to the formation of a transient protein radical and a covalent hemeprotein cross …

Significance: Failure to maintain myoglobin (Mb) in the reduced state causes the formation
of metMb, ferryl Mb species, and cross-linked Mb. Dissociation of ferriprotoporphyrin IX from …
