Description
Phytin, also known as inositol hexaphosphoric acid or phytic acid, is a major organic phosphorus compound found in seeds. It is a significant source of phosphorus for new seedlings until they begin to absorb it from the soil. Phytin consists of calcium and magnesium salts of inositol hexaphosphoric acid and is characterized by its chemical formula C12H30Ca5MgO54P12.
Uses
Used in Agricultural Applications:
Phytin is used as a fertilizer in the agricultural industry for its ability to be advantageously absorbed by plants. It serves as a valuable source of phosphorus, which is essential for plant growth and development. Phytin is also found in the soil as a product of the degradation of organic matter, contributing to the overall soil fertility.
Used in Soil Phosphorus Management:
In the field of soil science, phytin plays a crucial role in managing soil phosphorus levels. Myo-inositol hexaphosphoric acid (phytic acid), a component of phytin, is a major pool of organic phosphorus in the soil. It is fairly stable in an alkaline medium but gradually hydrolyzes in acidic conditions, releasing a range of intermediate inositol phosphates and eventually inositol. This process helps maintain the balance of available phosphorus in the soil, with myo-inositol phosphates accounting for between less than 1% and 62% of the total soil phosphorus.
Used in Microbial Research:
Phytin and its components, such as inositol phosphates, are thought to be of microbial origin. This makes them an important subject of study in the field of microbiology, as understanding their role in soil and their interactions with microorganisms can provide insights into nutrient cycling and soil health. The various stereoisomeric forms of inositol phosphates, including those of myo-, scyllo-, neo-, and chrio-inositol, have been characterized in soil, further contributing to the understanding of their role in microbial processes.
Check Digit Verification of cas no
The CAS Registry Mumber 7776-28-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,7 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7776-28:
(6*7)+(5*7)+(4*7)+(3*6)+(2*2)+(1*8)=135
135 % 10 = 5
So 7776-28-5 is a valid CAS Registry Number.

Conformational States of myo-Inositol Hexakis(phosphate) in Aqueous Solution. A 13C NMR, 31P NMR, and Raman Spectroscopic Investigation
Isbrandt, Lester R.,Oertel, Richard P.
, p. 3144 - 3148 (2007/10/02)
The longstanding question of the solution conformation of myo-inositol hexakis(phosphate) (IHP) has been resolved through combined use of NMR and Raman spectroscopic methods.IHP exists in aqueous solution in either of two conformations, depending on pH: the low-pH form possesses one axial and five equatorial phosphates (1-ax/5-eq), whereas the high-pH form has the inverted 5-ax/1-eq structure.Equal amounts of the two conformers coexist at pH 9.4 +/- 0.1 for 0.10 M Na12IHP at 27 deg C.The 13C NMR spectra of IHP (recorded over the pH range 0.5-12.5) are relatively insensitive to phosphate deprotonation, but do exhibit a single, major change in appearance centered around pH 9.4; this provides strong support for a conformational change.The 31P NMR spectra as a function of pH reveal, among other things, that the three least acidic phosphate protons have apparent pKa values of 9.2-9.6.The IHP ring inversion is most probably triggered by one or more of these acid-dissociation steps.The Raman spectra are sensitive both to acid dissociation and conformation, and also allow key spectral comparisons between aqueous solutions of IHP and solids of known structure (viz., solid Na12IHP having 5-ax/1-eq phosphates and solid myo-inositol having 1-ax/5-eq hydroxyls).Raman data indicate that alkali metal ions preferentially bind to, and thus stabilize, the aqueous high-pH IHP conformer in the order Li+ ca.Na+ > Cs+.The Raman spectrum of solid Ca6IHP is characteristic of the 1-ax/5-eq conformer, in contrast to the 5-ax/1-eq structure of the dodecasodium salt.
