P is also a component of
phytin, a major storage form of P in seeds.
Form 5ax/1eq is sterically hindered, generally referred to as
phytin, and can be stabilized upon formation of salt complexes with metal cations [2].
These effects are mediated by multiple active components, including erucic acid, isothiocyanate, phenols, and
phytin [159].
Phytic acid can be bound to two different metals such as Calcium ([Ca.sup.2+]) and Magnesium ([Mg.sup.2+]), the resulting mixed salt is called
phytin [4].
In the seed, phosphorus is stored in the salts of phytic acid, constituting
phytin, which, during germination, is degraded to release these nutrients in order to be used in the development of embryo and seedling (CARVALHO & NAKAGAWA, 2000).

phytin from soil.
Through its basic functions in plants as an energy source, phosphorus affects nodule development, production of protein, phospholipids and
phytin in grains legume (Rahman et al., 2008).
Four antinutritional factors, tannin (condensed), oxalate,
phytin bound phosphorus (
phytin P), and
phytin, were analyzed for the acridid.

The high concentration of phosphorus in the seed can be associated with the presence of
phytin, a compound considered to be a reservoir for phosphorus for germination (MENGEL; KIRKBY, 1987).
Phytin is a collective term for this mixed salt [40] and it constitutes up to 3% of many of the oilseeds and cereals used in animal feeds.
