Drawing Structures of Tetrapeptides

How to draw the structure of this tetrapeptide:


What type of bonding between amino acid residues is most important in holding a protein and polypeptide in a specific secondary configuration?

Solution Preview

Since alanine is listed first, this one must be the N-terminal. That means that it will expose its free NH2 group. Since threonine is listed last, it is the C-terminal. That means that it will have its COOH group free and exposed. We know this because primary structure of proteins are always listed with the N-term first.

The other piece of information we need is ...

Solution Summary

This solution explains structures of tetrapeptide and describes bonding between amino acids.
