LOL bacteria and viruses are everywhere! We would be so uncomfortable 24/7 and become germaphobes!
Answer:
A series of nonpolar amino acids would most likely be located in the interior region of the tridimensional molecule.
Explanation:
Proteins are formed by linearly arranged amino acids, each with a side chain: the R-group.
Of the 20 different amino acids that compose the proteins, about half of them -10- are non-polar. Their R-groups are not stable if they are in contact with water, meaning that non-polar amino acids are hydrophobic.
When proteins are synthesized, they acquire a three-dimensional structure that makes them more stable. Lineal polypeptides get folded and turn into a shape that makes them more stable in the environment and capable of accomplishing their biological role. When they are in an aqueous media, their bent shape leaves the hydrophilic R-groups in contact with water. The hydrophilic R-groups stick in the center of the polypeptide, facing the protein interior, and avoiding interaction with water.
