text: Yo, check it out, here's the rap rendition
  Keepin' it real, same content, no omission
  
  Listen up, y'all, 'bout this chemical compound
  3-Butene-1,2-diol, butenediol, renowned
  A metabolite of 1,3-butadiene, you see
  Detoxification or biotransformation, it can be
  
  Toxic metabolites, 3,4-epoxy-1,2-butanediol
  And hydroxymethylvinyl ketone, HMVK, oh well
  Butadiene exposure, it ain't no joke
  Comes with hexanes, biotransformation's common stroke
  
  We gotta find out if hexane has any effect
  On butenediol disposition, yo, we gotta inspect
  Urinary excretion of N-acetyl-S-(3,4-dihydroxybutyl)-L-cysteine
  That's the measure, MI level, if you know what I mean
  
  Genotoxicity and acute toxicity, gotta measure those too
  Bone marrow micronucleated erythrocytes, that's the clue
  Body weight changes, that's how we see the impact
  Rats are the subjects, yo, this study's on track
  
  Results show butenediol ain't genotoxic, no doubt
  To adult or immature rats, that's what it's about
  But it's acutely toxic to adult rats, gotta beware
  But the little ones, they're less sensitive, they don't care
  
  Yo, n-hexane co-exposure may ease the pain
  Attenuate the acute toxicity, that's the gain
  But remember, this is for adult rats, not the young
  Immature rats, they're different, not easily stung
