B. Pick any three different amino acids, link them together with peptide bonds, and draw the resulting short protein. Be careful to distinguish the amino and carboxyl ends from the side chains! Label the N and C ends. How would your peptide side chains interact with water? How would they interact with a lipid bilayer? You can write "INSIDE" or "OUTSIDE" after each of the amino acid one-letter codes listed here:

A. As the bulk solvent in biological systems, water exerts a huge effect on protein structure and
function by interacting strongly with certain amino acid side chains, but not with others. Take a
look at each the amino acid side chains (the circled parts on the next page) and decide whether
you would likely find each of them exposed to water on the outside surface of a soluble protein
or buried on the inside. Why?

Step 1
Amino acids are organic molecules containing an amino group and an acidic group hence the name amino acid.
The amino acids are linked together to form a peptide through the formation of a peptide bond. It releases one molecule of water. Any peptide will have two ends with an amine end and a carboxyl end.
