It may help to think of a concrete example. If you roll a standard six-sided die, the first roll has six possible combinations. The second roll also has six possible combinations; however, when paired with the first there are 6 x 6 possible sets of numbers. Provided the order of the numbers matters, when rolling a third time there are 6 x 6 × 6 possible sets of numbers. This pattern is 6" where r is the number of rolls.

- TERTIARY STRUCTURE (A) (B) (C) Fg Eet Galand Sen 20e Figure 6. Examples of the arrangement of a-helices and B-sheets in folded protein domains. Copyright 2013 from Essential Cell Biology, 4th Edition by Alberts et al. Reproduced by permission of Garland Science/ Taylor & Francis LLC. Figure 6 shows three examples of how secondary structure elements can be arranged in relation to one another in the functional, folded form of a complete protein or one compact portion of a protein. The overall three-dimensional shape (or conformation) of a protein is its tertiary structure. • What do you think holds together the various secondary structural elements in a particular three-dimensional pattern? (Hint: Look back at Figure 5 - what is sticking out from the sides of the a-helices and B-strands?)You will now build a 15 amino acid peptide using another paper or wire backbone as you did above. You will pick 15 amino acids, matching the criteria below, and put them onto your backbone about 3 inches apart. This will be the primary structure of your novel protein. Select 15 amino acids that meet the following criteria 6 hydrophobic R groups 2 acidic R groups 2 basic R groups 2 cysteine R groups 3 hydrophilic R groups Place the R groups in any order you choose on your paper or wire backbone as you did above. Start at the N-terminus and place each R group about 3 inches apart until all 15 are attached to the mini toolbar. You have just built the primary structure of your protein. Question 1: Record the sequence of amino acids in your protein, starting with the N-terminus. The N-terminus is the end of the polypeptide that has a free nitrogen group. The C-terminus, or carboxyl end, will have a free carboxyl group. You can use the three letter amino acid abbreviation to…The different types of interactions that stabilize the protein tertiary structure are illustrated in the diagram below.
