text: Yo, check it out, I'm here to spit some knowledge,
  Analyzing proteins with irregular ionization behavior, I won't acknowledge.
  Using a computational algorithm, countin' tautomers with precision,
  Titratable groups, polar hydrogens, no derision.
  
  Calculations on acid-acid, base-base, acid-base pairs,
  Even clusters of three groups, showin' what's there.
  PK values extracted from nonsigmoidal curves,
  They don't describe the ionization equilibrium, that's what I observed.
  
  Analytically derived, the conditions I found,
  For irregular curves when interacting groups are around.
  Tautomerization, it's connected, can't ignore,
  Irregular curves and tautomerization, they explore.
  
  The protonation-deprotonation equilibrium, let's get deep,
  Asp76 in ribonuclease T1, it's a secret I'll keep.
  Coupled to dipole reorientation, water molecule's bound,
  At the protein-solvent interface, chemical shift is found.
  
  So there you have it, the analysis is complete,
  Understanding proteins, ionization, and the beat.
  Rappin' about science, breakin' it down,
  Hope you learned somethin', turnin' your frown.
