text: Yo, listen up, here's a scientific rap
  'Bout the tammar wallaby and its milk's trap
  Casein levels rise as lactation rolls on
  Beta-casein's the star, alpha-casein stays strong
  
  Alpha-casein's phosphorylated to the core
  10-P's the form you'll find galore
  But beta-casein's phosphorylation takes a shift
  Late lactation brings lower values, a swift drift
  
  The enzymatic reaction can't keep up the pace
  With increasing beta-casein, it's a crazy race
  Unlike bovine casein, wallaby's got game
  Micelles stay intact, they ain't tamed
  
  At pH 7.0, calcium's not sequestered
  EDTA can't disrupt, it's not that tested
  Sodium dodecyl sulphate's the one to blame
  Complete disruption follows, it's a different game
  
  Hydrophobic bonds, they hold the micelles tight
  Keeping integrity, they shine so bright
  Wallaby milk's casein, despite the divide
  Assembles in micelles, just like bovine's pride
