Proteins are made of amino acids hooked end-to-end like beads on a necklace. To simulate. a protein, you will make a model of your protein using a long chenille stem (the fuzzy. covered wire) and colored beads.
When proteins are synthesized inside of a cell there are other special proteins (known as chaperones) that help in this process. Chaperones are proteins that bind to the newly synthesized protein or protein subunit, in order to ensure that the protein is properly folded into its secondary or tertiary structure.he secondary structure of a protein is the local organization of the primary sequence of the protein-helical or-sheet formations. The tertiary structure of a protein is the overall shape of the protein, caused by interactions between the various local structures.
