primary structure

of a segment of a polypeptide
https://doi.org/10.1351/goldbook.P04844
The amino acid sequence of the polypeptide chain(s), without regard to spatial arrangement (apart from configuration at the $\ce{\upalpha\mbox{-}carbon atom}$).
Note: This definition does not include the positions of disulfide bonds and is therefore not identical with 'covalent structure'.
