An amino acid isolated from a rare marine sponge can be represented by the general structure shown below:
The relative formula mass (MrM_rMr) of this amino acid is 117.
Calculate the relative formula mass of the section of this amino acid molecule represented by [R][\text{R}][R].
Relative atomic masses (ArA_rAr):
H=1C=12N=14O=16 \text{H} = 1 \quad \text{C} = 12 \quad \text{N} = 14 \quad \text{O} = 16 H=1C=12N=14O=16
