The striated muscle of mammals have a similar chemical composition to the one found in other body tissues. So, it is composed of 70 % of water and 30 % of solid matter. However, the striated muscle's solid matter consists in turn of proteins (myosin and myogen), nitrogen-containing matters (creatine, adenyl-pyrophosphoric acid, and myoglobin), minerals (calcium, magnesium, iron, potasium, phosphorus, sulfur, etc.), aminoacids, carnitine, glycogen, and lactic acid. Proteins represent about 80% of the muscle solid matters. Myosin is globulin, and myogen is an albumin. Creatine is found in combined with phosphoric acid as phosphocreatine.
