Crystalline barium salts have been prepared and analyzed which 

 correspond to the following formulas, C 6 H 12 O 24 P Ba 3 and (C 6 H 11 24 P 6 ) 2 

 JBa 7 . 



Salts of other metals are generally obtained as amorphous pre- 

 cipitates. 



The acid yields readily crystalline strychnine salts. 



The free acid may be obtained as a colorless, non-crystallizable 

 syrup. 



The acid decomposes on complete hydrolysis, yielding inosite and 

 phosphoric acid. 



On partial hydrolysis of the substance phosphoric acid and various 

 lower inosite tetra-, tri-, di- or monophosphoric acids are produced. 



When inosite and dry phosphoric acid are heated in vacuum to a 

 temperature of 140 to 160° a reaction occurs and inosite tetraphos- 

 phoric acid is formed. 



Inosite monophosphoric acid is formed from inosite hexaphos- 

 phoric acid on partial hydrolysis with mineral acids or by the action 

 of the enzyme phytase in dilute acid solutions. 



Wheat bran contains an enzyme phytase which in faintly acid 

 solution rapidly hydrolyzes the inosite phosphoric acid with the pro- 

 duction of inorganic phosphoric acid and various lower inosite phos 

 jihoric acids and some free inosite.
