Proteins provide structure and support for living organisms, and are found in many types of foods, such as meat, eggs, milk, rice, and beans. Proteins are made up of a chain of monomers called amino acids. The picture to the right is a protein, and the circles represent amino acids. Our bodies need 20 different amino acids in order to make up all the different proteins required to keep us healthy. The amino acids combine in different order in different proteins because the order of the amino acids affects the structure and job of the protein. There are many types of proteins in our body. In this activity, you will create beaded chains that represent this important macromolecule! Procedure 1. Read through the first protein description on your worksheet. 2. Fill in the color of beads needed for each of the amino acids of the protein using the chart below. 3. Get a piece of string and the beads you need and make each protein. 4. Repeat 1-3 for each of the proteins listed on your worksheet. 5. Answer questions 1-7 on your worksheet. 6. Put your string and your beads back into the correct containers. Turn in your worksheet and place these instructions in the middle of your table. Table 1.
