Myoglobin-structure, function, and medical importance

This research provides a contemporary review of Myoglobin (Mb), the oxygen-binding protein in muscle. It focuses on its unique molecular structure, multifaceted functions (oxygen storage, nitric oxide regulation, intracellular oxygen transport), and its critical medical importance as a biomarker in the early diagnosis of myocardial infarction and rhabdomyolysis, while exploring its emerging role in cancer biology.
