Question

Phenylalanine and threonine are amino acids that each contain a carbon ring as their r-group. threonine additionally has a hydroxyl group. given this information, what would you expect to find in a globular protein? *

Answer 1

Based on the information given above, phenylalanine, which has only carbon rings as its R group will be find in the interior part of the globular protein while threonine which has both carbon ring and hydroxyl groups will be found in the exterior part of the globular protein. This is because, globular proteins are folded in such a way that their tertiary structures is made up of polar amino acids arranged at the exterior part while the non polar amino acids are arranged in the interior part.
