Answer
An amino acid is the building block of proteins. In the context of the protein structure, it represents the primary structure when considered individually, which is a linear sequence of amino acids.

Answer
A polypeptide is a chain of amino acids linked by peptide bonds. It represents a primary structure as well but may also contribute to secondary structures when it folds into specific shapes due to interactions within the chain. Thus, if X refers to a polypeptide, the answer would be 'Primary structure'.
