Let's look at another dipeptide.Let's look at another dipeptide.
Identify each amino acid in this dipeptide.
|
What is the short-hand notation for this dipeptide?
Identify which amino acid is at the N-terminus and which is at the C-terminus.
Identify the α carbons of each amino acid.
Identify the atoms involved in the peptide bond in this dipeptide.
Now, measure the distance between the α carbons.
To measure a distance, Double click on the first atom, then double click on the second atom. You may need to rotate the molecule a bit to see the distance well. Try it now.
Write down this distance and submit it to your instructor.

Now you are ready to work with oligopeptides, or polymers composed of 3-20 amino acid residues. These polymers are linear; that is, each amino acid is linked to it's neighbor in a head-to-tail fashion rather than forming branched chains. You will be observing a 5mer in this tutorial.
