There are three different types of myofilaments: thick, thin, and elastic filaments. Thick filaments consist primarily of the protein myosin. Each thick filament is approximately 15 nm in diameter, and each is made of several hundred molecules of myosin. A myosin molecule is shaped like a golf club, with a tail formed of two intertwined chains and a double globular head projecting from it at an angle.
Protein is composed of amino acids, which are in turn made up of mostly carbon, hydrogen, oxygen, and nitrogen. A few amino acids also contain sulfur: both Cysteine and Methionine. Thus, proteins containing these amino acids would be made up of very small amounts of sulfur, in addition to the more common elements listed above. The five chemical elements of protein are, 1.) sulfur 2.) carbon 3.) hydrogen 4.) oxygen 5.) nitrogen.
