Peptide 2:
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.
