Identify the preferred orientation of amino acid side chains in the tertiary structure of a protein in an aqueous environment.

A. The hydrophobic side chains will prefer to be on the interior where they can interact with water molecules in the aqueous environment.

B. The hydrophilic side chains will prefer to be on the exterior where they can interact with water molecules in the aqueous environment.

C. The hydrophilic side chains will prefer to be on the interior where they can avoid interacting with water molecules in the aqueous environment.

D. The hydrophobic side chains will prefer to be on the exterior where they can avoid interacting with water molecules in the aqueous environment.

Answer #1

Answer:

Amino acid side chains can be hydrophobic or hydrophilic. The side chains which prefer to stay away from water molecules are called hydrophobic side chains. On the other hand, hydrophilic side chains prefer to interact with water molecules.

Hydrophobic side chains remain in the interior of a protein structure, so that they remain shielded against water molecules of external environment.

Hydrophilic side chains remain on the exterior of protein molecules, so that they can interact with water molecules present in external environment.

Hence, correct choice should be :

B. The hydrophilic side chains will prefer to be on the exterior where they can interact with water molecules in the aqueous environment.

    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.

    6) Proteins are composed of amino acids polymerized into long chains. The structure of a protein - that is, its overall shape and how the chains are "folded” around each other - is very important for its function. In an aqueous environment, in an active, folded state the hydrophilic amino acids in the protein are facing outwards exposed to the water and the hydrophobic amino acids are hidden away from the water in the core of the protein. In a...
