AP Biology Unit 1.5 AP Exam review Questions and Answers How does a non polar R group substitution affect the folding of a protein? A non polar R group substitution can change the structure of a protein because it will cause the protein to fold differently. This different folding will cause the Non polar region to fold inward. Due to the fact that structure controls function, the substitution of a non polar R group will result in a change in function due to the structure change How does ...
