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.
Nitrogen (3%) is found in many organic molecules, including the amino acids that make up proteins, and the nucleic acids that make up DNA. Calcium (1.5%) is the most common mineral in the human body â nearly all of it found in bones and teeth.
