Phytate and cation binding activity
Since O'Dell and Savage, reported in 1960 that phytate decreased the bioavailability of zinc, the negative, antinutrient properties of phytate have been well documented. But the chemical activities of phytate remain largely unknown. Recently, under the perception of weight control and healthy life, …

The utilization of phytate-phosphorus by the transition dairy cow
<p>Phytate phosphorus (pP) availability in rumen fluid was analyzed during the transition period of two heifers by in vitro and in situ incubations. Apparent digestibility (AD) of P during the transition period was measured and P balance determined. The study included three periods, a prepartum …

Rapid Phytate Quantification in Manures and Runoff Sediments using HPIC
… to understanding P dynamics in the environment. Phytate is an organic form of P, with 6 phosphate groups, which is found in manures, but is difficult to quantify due to its affinity for complex formation with aluminum (Al) and iron (Fe). The objective of the first study was to measure if high …

Quantification and alleviation of the antinutritional effects of phytate on poultry
… feed materials is in the unavailable form of phytate (inositol hexaphosphate or phytic acid). Phosphorus supplements are expensive and over supplementation can increase excretion of P, with negative implications on the environment. For some time, research has focussed on the development of …

Phytate Extraction and Stimulation of Phytase by Zn & Mg in Seeds
… water for 0, 2, 6, 18 and 24 hours, and the phytate in the seeds and in the soak water was quantitatively analyzed. A comparison of phytate content was made after the seeds were soaked in 0.01 N HCl or in saturated NaHco 3. The seeds soaked in distilled water served as controls. The effects …

Development of New and Alternative Resources for Breeding Low Phytate Soybeans
… Merr) cultivars with genetic reduction in seed phytate concentration will be a valuable resource to livestock producers both nutritionally and economically, as well as in the preservation of the environment. However, due to association with reduced seed germination and field emergence potential, …

The Genetic Basis of Phytate, Oligosaccharide Content, and Emergence in Soybean
… in soybean seeds is found in the form of phytate, but because of its negative nutritional and environmental impacts, seed phytate and raffinosaccharide content have been a recent focus of breeders and molecular geneticists. The soybean line CX1834 is a low phytate mutant known to have two …

Metabolomic Discrimination of Near Isogenic Low and High Phytate Soybean [GLYCINE MAX (L.) MERR.] Lines
Phytate is the major storage form of phosphorus in seeds of soybeans. Because phytate chelates mineral cations including calcium, iron, and zinc, these mixed salts are often excreted by non-ruminant animals such as humans, swine, poultry, and fish. While this causes iron and zinc deficiencies, …

The effect of inositol-hexakisphosphate (phytate) on urinary risk factors for calcium oxalate urolithiasis in South African population groups with different kidney stone risk profiles : theoretical modelling, in vitro crystallisation experiments and in vivo human studies
… thesis were to establish whether soluble calcium-phytate complexes inhibit calcium oxalate crystallisation and whether a higher dietary intake of phytate in South African black subjects compared to white subjects may contribute to the relative rarity of urolithiasis in this group. Potentiometric …

Improved iron and zinc availability in sorghum by phytate reduction through genetic modification, fermentation and phytase addition
… sorghum contains the most iron, it also contains phytate and sometimes also tannins, depending on the cultivar, which further reduce the already low bioavailability of non-haem iron and zinc. The aim of this research was to evaluate the effect of reducing sorghum and maize phytate content through …

Genome and Transcriptome Based Characterization of Low Phytate Soybean and Rsv3-Type Resistance to Soybean Mosaic Virus
Soybean is a dominant oilseed cultivated worldwide for its use in multiple sectors such as food and feed industries, animal husbandry, cosmetics and pharmaceutical sectors, and more recently, in production of biodiesel. Increasing demand of soybean, changing environmental conditions, and evolution …

LOW-PHYTATE GRAINS TO ENHANCE PHOSPHORUS SUSTAINABILITY IN AGRICULTURE: GENETIC ANALYSIS ON THE LOW PHYTIC ACID1-1 MAIZE MUTANT
Background: Phosphorus is an essential component of fertilizers and feed and in recent decades has become one of the main sustainability issues as a non-renewable resource. In plant seeds, the main reserve of phosphorus is phytic acid, a strong anti-nutritional factor for monogastrics and a …

Dietary diversity and micronutrient intake in women in North West UK and North West Pakistan: the impact of phytate
… consumed in SA countries contain high amount of phytates, which are known for inhibiting micronutrient absorption. Considering this, the purpose of the present study was to assess dietary diversity among SA women in northwest UK (NW UK) and northwest Pakistan (NW PK), along with investigating the …

Mapping Quantitative Trait Loci for Soybean Quality Traits from Two Different Sources
… remained high and the oligosaccharide and phytate contents were lowered to make soybeans more acceptable for human and animal consumption. A soybean population of 55 families segregating for genes controlling quality traits was chosen for this study. Both parental lines have high sucrose …
