In most cases the peptide bond is in the trans conformation. What statement below best explains this observation? a) The peptide bond has double bond character that prevents free rotation. b) In the cis conformation the R groups cause steric hindrance. c) In the trans conformation the carbonyl oxygen and the amine hydrogen can participate in hydrogen bonding. d) In the trans conformation the angle strain is reduced. e) All of the above explain the observation. while all statements might be true they do not explain the phenomenon

Expert Solution
Step 1
In proteins the adjacent amino acids are held together via peptide bonds .
A peptide bond is an amide bond that is formed between the α-nitrogen atom of one amino acid and the carbonyl carbon of the amino acid adjacent to it.
Peptide bonds are planar and rigid and helps to stabilize protein structure.
