D-myo-Inositol-1,2,3,5,6-pentaphosphate (sodium salt)

D-myo-inositol-1,2,3,5,6-pentaphosphate (Ins(1,2,3,5,6)-P5) (sodium salt) is produced from Ins(1,2,3,4,5,6)P6 via a minor enzymatic phytate degradation pathway by K. terrigena. Ins(1,2,3,5,6)-P5 (sodium salt) is minimally effective in opening calcium channels relative to Ins(1,4,5)P3.Formal Name: D-myo-inositol-1,2,3,5,6-pentakis (dihydrogen phosphate), pentasodium salt.
