The result is also in line with the report of Modi and Asanzi (2008) that Magnesium was confirmed to be a major constituent of chlorophyll, protochlorophyll, pectin and phytin
in maize; and the crop Mg removal is 40 kg [ha.sup.-1] MgO.
Structure and function of metal chelators produced by plants: the case for organic acids, amino acids, phytin
However, a large part of the phosphorus in seeds and grains (and their by-products) is in the form phytin
, an organic phosphorus compound, and this is not well assimilated by some animals--especially poultry, but including pigs.
Digestibility of phytin

Phytase is an enzyme that degrades phytin
or phytic acid.
is one of the most important forms of organic P in soil.
myo-Inositol is important in the synthesis of phytin
, galactinol, raffinose, and stachyose in soybean seeds and is synthesized by myo-inositol phosphate synthase (MIPS; EC 188.8.131.52; Hegeman et al., 2001; Hitz et al., 2002) and myo-inositol monophosphatase (IMP1; EC 184.108.40.206; Ishitani et al., 1996; Styer et al., 2004).
Early EB, Turk EE (1944) Time and rate of synthesis of phytin
in com grain during the reproductive period.
Organic Phosphate: (i) Phytin
, inositol hexaphosphates 940-50%); (ii) Nucleic acid and its nucleotides (0.6%).
As is the case with most plants, the phosphorus in soybean meal is present largely as phytic acid (phytin
) phosphorus, which is biologically unavailable to the pig.
