High Ca 2+ concentration can enhance BPP catalysis rate up to a limit. When Ca 2+ concentration surpasses this limit, extra Ca 2+ ions begin to work as competitive inhibitors. High concentrations of free phytate which not bound to Ca 2+ also inhibits BPPs. This happens possibly via free phytate mediated chelation of the Ca 2+ bound to BPPs. [4]
Phytic acid (deprotonated phytate anion in the picture) is an antinutrient that interferes with the absorption of minerals from the diet.. Antinutrients are natural or synthetic compounds that interfere with the absorption of nutrients. [1]
The hexavalent phytate anion. Phytic acid was discovered in 1903. [2] Generally, phosphorus and inositol in phytate form are not bioavailable to non-ruminant animals because these animals lack the enzyme phytase required to hydrolyze the inositol-phosphate linkages. Ruminants are able to digest phytate because of the phytase produced by rumen ...
Phytate. A phytase (myo-inositol hexakisphosphate phosphohydrolase) is any type of phosphatase enzyme that catalyzes the hydrolysis of phytic acid (myo-inositol hexakisphosphate) – an indigestible, organic form of phosphorus that is found in many plant tissues, especially in grains and oil seeds – and releases a usable form of inorganic phosphorus.

The IP user is thinking of phytate, which is the general term for the salt form of IP6. Phytin refers specifically to the calcium or magnesium salt of IP6. Most literature discussing the storage of phosphate and chelation of cations in plant seeds stick to the term phytate because it is the general term for the salt.
"A lot of people will falsely present with an autoimmune disease, like fibromyalgia or rheumatoid arthritis, when the underlying cause is an infection that goes undiagnosed and untreated," he noted.
The so-called "classical 3-point MACE" is defined as a composite of nonfatal stroke, nonfatal myocardial infarction, and cardiovascular death. [4] [5] Another study similarly defined MACE as a composite of nonfatal stroke, nonfatal acute coronary syndrome, and death from vascular causes. [6]
In suitable environments, biomolecules like chlorophyll can be transformed and preserved in recognizable forms as biomarkers. Conversion during diagenesis often causes the chemical loss of functional groups like double bonds and hydroxyl groups. Pristane and phytane are formed by diagenesis of phytol under oxic and anoxic conditions, respectively.
