A sensitive method for the quantification of the mass of inositol phosphates using gas chromatography-mass spectrometry

open access: yesJournal of Lipid Research, 1990
A sensitive method to directly measure the mass of inositol phosphates from biologic samples is described. The procedure uses ammonium sulfate gradient elution anion exchange column chromatography to isolate inositol monophosphate, bisphosphate ...

A Role for Phosphoinositides in Regulating Plant Nuclear Functions

open access: yesFrontiers in Plant Science, 2012
Nuclear localized inositol phospholipids and inositol phosphates are important for regulating many essential processes in animal cells such as DNA replication, recombination, RNA processing, mRNA export and cell cycle progression.

Intracellular signalling: Inositol phosphates –  whither bound? [PDF]

open access: yes, 1996
Many proteins are being found to bind inositol phosphates with varying degrees of specificity; the variety of domains that can bind inositol phosphates suggests convergent evolution, but the functions of most of the binding sites are not yet ...

Certain Malvaceae Plants Have a Unique Accumulation of myo-Inositol 1,2,4,5,6-Pentakisphosphate

open access: yesPlants, 2015
Methods used to quantify inositol phosphates in seeds lack the sensitivity and specificity necessary to accurately detect the lower concentrations of these compounds contained in the leaves of many plants.

A novel method for the purification of inositol phosphates from biological samples reveals that no phytate is present in human plasma or urine [PDF]

open access: yesOpen Biology, 2015
Inositol phosphates are a large and diverse family of signalling molecules. While genetic studies have discovered important functions for them, the biochemistry behind these roles is often not fully characterized.

Lactic acid and thermal treatments trigger the hydrolysis of myo-inositol hexakisphosphate and modify the abundance of lower myo-inositol phosphates in barley (Hordeum vulgare L.). [PDF]

open access: yesPLoS ONE, 2014
Barley is an important source of dietary minerals, but it also contains myo-inositol hexakisphosphate (InsP6) that lowers their absorption. This study evaluated the effects of increasing concentrations (0.5, 1, and 5%, vol/vol) of lactic acid (LA ...

Inositol metabolism as a broad-spectrum antiviral target

open access: yesFrontiers in Microbiology
Inositol plays many important roles in cellular processes through its various derivatives including phosphatidylinositol phosphates. Viruses use phosphatidylinositol phosphates for their replication in multiple processes including entry, formation of ...

HPLC Separation of Inositol Polyphosphates

open access: yes, 2010
High performance liquid chromatography (H PLC) is an essential analytical tool in the study of the large number of inositol phosphate isomers. This chapter focuses on the separation of inositol polyphosphates from [H-3]myo-inositol labeled tissues and ...

The Impact of Mash pH and Exogenous Phosphorolytic Enzymes on the Release of Inositol Phosphates, Fermentable Sugars and Polypeptide Profile in the Technology of Buckwheat Beer

open access: yesBulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Food Science and Technology, 2022
The first - already published - stage of the project, which conducted optimization of the temperature mashing program, yielded promising results in the form of an increase in the pool of bioactive myo-inositol by 50% in buckwheat wort supplemented with ...
