Biochemistry
Muscular  tissue makes up to 40% of the weigh of the human body.

Muscular tissue contains protein which has collagen derived from its connective tissue; cell nuclei containing nucleoprotein. Other proteins include

  • Myogen

  • Myoglobin

  • Globulin X

  • Actin

  • Myosin

  • Tropomyosin

  • Actinin

  • Desmin

  • Myomesin

  • Titin

Others chemical substances  include

  • Lipids

  • Carbohydrate

  • Pigment which is mainly myoglobin and some cytochromes.

  • Inorganic salts such as potassium phosphate.

Muscle tissue contains 70.1% of water, 21.9% of protein, 6.6% of lipid and ash is 1.0%
