The proportion of phytic acid is up to 10-30 g/kg of the dry matter of cereal, legume and oilseeds and con- stitutes the major portion of total phosphorus m the seed. In organic chemistry, phosphonates or phosphonic acids are organophosphorus compounds containing C−PO(OR)2 groups (where R = alkyl, aryl, or just hydrogen). Phosphonic acids, typically handled as salts, are generally nonvolatile solids that are poorly soluble in organic solvents, but soluble in water and common alcohols. Many commercially important compounds are phosphonates, including glypho…
