text: In 19 wheat-millin' fractions, yo,
  Pentosan content be calculatin' like so,
  0.88 times the sum of L-arabinose and D-xylose,
  1.44 to 30.66 percent, dry matter, it shows.
  
  When the ash content exceeded 0.6 percent,
  The pentosan content increased, yo, it went intense.
  Water-extractable arabinoxylans we did retrieve,
  From the water extracts, 65 percent ethanol, believe.
  
  In the millin' fractions, the content varied wide,
  0.35 to 1.38 percent, no need to hide.
  And above 0.6 percent ash, it did rise,
  Arabinoxylan content increased, reachin' the skies.
  
  L-arabinose-to-D-xylose ratios, we did find,
  Ranged from 0.65 to 0.39, ain't nothin' blind.
  The fractions with high ash had the lowest score,
  Ash-rich tissues contain less-branched arabinoxylans, for sure.
  
  Now let me drop some knowledge 'bout what we found,
  In the (1)H NMR spectroscopy, we got around.
  Decrease in L-arabinose-to-D-xylose ratio, it's true,
  Led to more unsubstituted xylose, and less of the two.
  
  Disubstituted xylose residues went on a decline,
  While monosubstituted xyloses, they stay fine.
  Content of those remained virtually the same,
  That's the rap, hope y'all got the game.
