Question

Simple proteins consist of amino acids linked together in a long chain; a small portion of such a chain is

Answer 1

While there is some restriction on rotation around a double bond, it is possible to rotate around a single bond. The C-N bond (shown by the arrow) acquires certain double bond characteristics through resonance. As a result, the C-N double bond prevents the bond from rotating.

What is a chemical bond?

A chemical bond is a strong bond that can be formed between atoms, ions, or molecules to create chemical compounds. In covalent bonds, the electrons are shared, whereas, in ionic bonds, the electrostatic attraction of two ions with opposing charges forms the link. In contrast to dipole-dipole interactions, the London dispersion force, and hydrogen bonding, which are examples of "weak bonds" or "secondary bonds," covalent, ionic, and metallic bindings are examples of "strong bonds" or "primary bonds."
