Question

question 5 (1 point)
what is the polarity of the side chain (highlighted in the box) of the amino acid shown?
a) non polar
b) polar

Explanation:

The side - chain in the box consists of only carbon and hydrogen atoms. Carbon - carbon and carbon - hydrogen bonds are non - polar (since the electronegativity difference between C and C is 0, and between C and H is very small, about 0.4). Non - polar bonds result in a non - polar side - chain.

Answer:

A. Non polar
