text: Boronic acids and boronate esters, yo, chemical biology's besters,
  Orthogonal pairs, metal-catalyzed affairs,
  Sequential cross-couplings, prepare bioconjugates rare,
  Protein-protein conjugates, complex and so flair.
  
  In this paper, we expand, bis-boronic acid in hand,
  Tandem covalent, dynamic bioconjugation, grand,
  2-nitroarylboronic acid, with cysteine it bonds,
  Phenylboronic acid, with salicylhydroxamic acids, fond.
  
  Under physiological conditions, yo, it goes down,
  Bioconjugates formed, dual linkages renowned,
  Covalent and dynamic, a reversible sound,
  Add unfunctionalized SHA, or reactive oxygen, rebound.
  
  Small molecules, macromolecules, proteins too,
  Amenable with this approach, that's what we do,
  Reversible, reversible, with SHA in view,
  New insights, kinetic stability of SHA adducts, true.
