  1. What types of reactions make polypeptides? Break them down?
  2. What different types of chemical interactions contribute to protein structure?
  3. Explain the different levels of protein structure and how they contribute to the shape of the protein. What are the shapes associated with secondary structure?

Homework Answers

Answer #1

Polypeptides are made up of peptides. Peptides are in turn made up of amino acids

So, amino acids are the building blocks of proteins.

Proteins are formed by the dehydration reaction.

In this reaction when two amino acids combine a molecule of water is removed.

So, this reaction is called as dehydration reaction.

Proteins are broken down by hydrolysis reaction.

In this reaction a molecule of water is used to break peptide bonds.

So, a protein is made by dehydration reaction and it is broken by hydrolysis reaction.
