WebNov 9, 2024 · Myoglobin is a small, oxygen-binding protein found in heart and skeletal muscles. When heart or skeletal muscle is injured, myoglobin is released into the blood and eliminated from the body in the urine. A myoglobin blood test may be used to detect muscle damage and a myoglobin urine test may reflect muscle damage and risk of kidney damage. WebIt 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. [ 3] Myoglobin is critical to skeletal muscle O 2 supply at near-maximum oxygen demand, and prevents anoxia by maintaining PO 2 above levels needed to support mitochondrial function.
