Answer
The primary structure of a protein is primarily determined by the sequence of amino acids and is held together by covalent bonds. Unlike secondary and tertiary structures, which involve hydrogen bonds and hydrophobic interactions that can be disrupted by heat, the primary structure remains intact under increased temperatures up to a certain limit.
