"no: external catalysts, heat, light... modification creates new class of fully recyclable polymers... polyethylene analogs manufactured, used, converted back into their original building blocks—enabling closed-loop chemical recycling... sulfur-sulfur bonds fundamental to peptide/ protein structure, so discovery provides a new tool for biologists to manipulate protein structures without damaging sensitive biological components... selectively modifies anti-tumor compound calicheamicin"
