Some of the typical scenarios are: The narrator may be of a dramatically different age than the people in the story, such as a child attempting to explain adult actions. The narrator may have prejudices about race, class or gender. The narrator may have low intelligence.
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.
Humans have tens of thousands of different proteins, each with a specific structure and function. Proteins are the most structurally complex molecules known. Each type of protein has a complex three-dimensional shape or conformation. All protein polymers are constructed from the same set of 20 amino acid monomers. Polymers of proteins are called polypeptides. A protein consists of one or more polypeptides folded and coiled into a specific conformation. Amino acids are the monomers from which proteins are constructed. Amino acids are organic molecules with both carboxyl and amino groups. 1  At the center of an amino acid is an asymmetric carbon atom called the alpha carbon. 2  Four components are attached to the alpha carbon: a hydrogen atom, a carboxyl group, an amino group, and a variable R group (or side chain).
