proteiinirungosta
Proteiinirungosta, which translates to "protein backbone" in English, refers to the continuous chain of amino acids linked by peptide bonds in a polypeptide. This fundamental structure is the linear sequence of atoms that forms the core of a protein molecule. It is formed by the repeating unit -N-C-C- where N represents nitrogen, C represents carbon, and the first C is the alpha-carbon of an amino acid, followed by the carbonyl carbon.
The amino acid side chains, also known as R-groups, are attached to the alpha-carbon atoms of this
The protein backbone itself has some intrinsic flexibility due to the rotational freedom around certain bonds,
