Proteins that differ inthe order or type of amino acids they contain may have very different structuresand functions. In fact, a change in even a single amino acid can sometimes affectthe way a protein works.To see how many unique proteins, each composed of just two amino acids,can be formed from five different amino acids, fill in the spaces in the tablebelow. Some of the spaces have been filled in to show you how. Assume that eachletter represents a different amino acid.Amino AcidsABDEAAAАВACBACEAnswer the following questions in the spaces provided.1.

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…

When an inappropriate amino acid is substituted in place of another, as occurs in certain genetic disorders, the resulting protein is either poorly functional or non-functional. Since proteins contain hundreds if not thousands of amino acids, why should the change of a single amino acid be so critical?
Assume you were given a mixture consisting of one molecule each of all possible sequences of a smallish protein of molecular weight 4800 daltons. If the average molecular weight of an amino acid is, say, 120 daltons, how much would the sample weigh? How big a container would you need to hold it?
