text: Yo, check it out, I got something to say,
  'Bout the proteins in the eye lens, makin' their way.
  As we age, they accumulate modifications,
  Chemical changes, no time for vacations.
  
  Carbonyls and oxidative stress go hand in hand,
  Drivin' those modifications, they're in command.
  Oxidative stress messes with glutathione and ascorbate,
  Breakin' 'em down, causin' a nasty debate.
  
  The result? Dicarbonyl compounds, highly reactive,
  Formin' advanced glycation end products, that's the objective.
  AGEs cause crosslinkin' and protein aggregation,
  Contributin' to lens aging and cataract formation.
  
  But hold up, there's hope, a solution we've found,
  A compound called carboxitin, holdin' its ground.
  Linkin' GSH diester and mercaptoethylguanidine,
  Fightin' against AGE formation, we ride.
  
  When we cultured bovine lens with carboxitin in sight,
  GSH and mercaptoethylguanidine reached new heights.
  It inhibited protein crosslinkin', AGE formation too,
  Even stopped 3-deoxythreosone, a precursor that grew.
  
  Carboxitin kept stiffness at bay, no increase in strain,
  In organ-cultured mouse lenses, it showed its domain.
  Deliverin' carboxitin to the lens, boostin' GSH levels,
  Trappin' those dicarbonyl compounds, no time for revels.
  
  This compound's got potential, a therapy in the making,
  Fightin' against AGEs, stiffness it'll be breaking.
  Say goodbye to presbyopia, that lens-related strife,
  Carboxitin's the answer, bringin' a better life.
