Amino acids are the materials the cell actually uses for the building of the protein. In this module, we will use the letters of the alphabet to represent the amino acids all species used to build all their proteins. The bottom of a Web site chart of amino acids shows the real names of the amino acids represented by each letter. Like the different arrangement of nucleotide beads on the double-stranded DNA necklaces had different characters, so different arrangements of amino acid links in the protein chain have different characters. The different sequences of amino acids in the chain give the proteins different properties.
Some proteins become enzymes which speed up chemical reactions.
Some become fibers that hold the bodies of organisms together. All of it is determined by the sequence of amino acids in the protein. The next web link will look like the diagram below. To discover the amino acid sequence of your protein proceed with the following list. The site will retrieve for you a list of articles about your protein's amino acid sequence.
