Best Answer

rigid because of the resonance stabilization of the amide (peptide) bond and the C=O (C double bond O) cause the structure to be planar and is therefore incapable of rotation.

It is due to sp2 hybridization and planar structure of carbonyl carbon.

Why do peptide bonds act as a double bond?

They don't, exactly. However, both the nitrogen and the carbon participating in the bond are in the sp2 hybridization state, and this allows for a resonance structure making the group planar and restricting rotation about the carbon-nitrogen bond.
