WebNov 9, 2024 · Myoglobin is a small protein found in heart and skeletal muscles that binds oxygen. It traps oxygen within muscle cells, allowing the cells to produce the energy required for muscles to contract. When heart or skeletal muscle is injured, myoglobin is released into the blood. Elevated levels can be measured within a few hours following an injury. WebFor a myoglobin solution of concentration 1 g 1-1, e- w-= 0.1 5 which for a value of e= 100 would give p = 0.0075.
