Structure and function of myoglobin
WebMyoglobin, in muscle cells, accepts, stores, transports and releases oxygen. About 6 percent of body iron is a component of certain proteins, essential for respiration and energy metabolism, and as a component of enzymes involved in the synthesis of collagen and some neurotransmitters. Iron also is needed for proper immune function. WebMyoglobin (symbol Mb or MB) is an iron- and oxygen-binding protein found in the skeletal muscle tissue of vertebrates in general and in almost all mammals and works like a …
