-What is the nature of amino acids on the surface of a water soluble (Globular) protein - polar or nonpolar? Explain using hydrophobic interactions.
Homework Answers
Hydrophilic Polar Amino acid will be on surface of globular proteins so that they can interact with water which is also polar and non polar , hydrophobic amino acid will be inside of protein .

Even though hydrophobic amino acids tend to be buried in the interior of a globular protein, polar neutral and polar charged amino acids are found in the interior of a globular protein as well. Recall Figure 4.26 of myoglobin. To see how this can happen, consider a model of a generic globular protein (below). The side chains of only seven of the amino acids are shown. 5. "DH" is a side chain that is a hydrogen bond donor "A" is...
Consider the following amino acids. Based off their side chains
4. Consider the following amino acids. Based off their side chains, which would you suspect to be the most prevalent in the hydrophobic core of a protein. Justify your response. 5. Are the hydrophobic interactions caused by the repulsion between water and nonpolar molecules? Explain in your own words what happens to the water structure near hydrophobic molecule? Is water special?

Lumpur QUESTION 2 Myoglobin is a globular protein. About half of its 153 amino acids have nonpolar side chains. Where would you expect those amino acids to be located in the tertiary structure? Inside the compact tertiary structure Outside the compact tertiary structure Evenly distrubuted On the edges of the amino acids primary chain QUESTION 3 What type of bonding is responsible for the primary structure of a protein? covalent bonds hydrogen bonds ionic bonds alpha helices

For the tertiary structure of proteins in an aqueous/polar environment, hydrophobic amino acids are located on the surface of the protein whereas non-polar amino acids are located in the interior. Let’s assume that the protein was normally in an environment with just the opposite composition, that is a non-polar, hydrophobic environment (for example liquid methane). What would the orientation of the polar and non-polar amino acids be? Explain.
