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.
1 Proteins are macromolecules that consist of long, unbranched chains of amino acids. 2  These chains may contain about 20 up to hundreds of amino acids. 3  An example of the size of proteins is the red pigment in red blood cells called haemoglobin with the chemical formula-C 3032 H 4816 O 872 N 780 S 8 Fe 4. Proteins are macromolecules made from amino acids, nucleic acids are made from nucleotides, carbohydrates are made from monosaccharides or simple sugars, and lipids are made from fatty acids and glycerol.
