Drag the structure with the mouse to rotate

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.
