Application

Myoglobin from equine skeletal muscle was used in a study to test experimental protein mixture for validating tandem mass spectral analysis.

Biochem/physiol Actions

Myoglobin from horse skeletal muscle is a single chain heme protein containing 153 amino acid residues. It possesses no disulfide bridges or free -SH groups. Myoglobin contains 8 variously sized right-handed helical regions, joined by non-ordered or random coil regions.
Myoglobin is critical to skeletal muscle O2 supply at near-maximum oxygen demand, and prevents anoxia by maintaining PO2 above levels needed to support mitochondrial function.
