Phytic acid
myo-Inositol hexakisphosphate is an intermediate in inositol phosphate metabolism. It can be generated from D-myo-inositol 1,3,4,5,6-pentakisphosphate via the enzyme inositol-pentakisphosphate 2-kinase (EC 2.7.1.158). myo-Inositol hexakisphosphate is also known as phytic acid. It can be used clinically as a complexing agent for the removal of traces of heavy metal ions. It acts also as a hypocalcemic agent. Phytic acid is a strong chelator of important minerals such as calcium, magnesium, iron, and zinc and can, therefore, contribute to mineral deficiencies in developing countries. For people with a particularly low intake of essential minerals, especially young children and those in developing countries, this effect can be undesirable. However, dietary mineral chelators help prevent over-mineralization of joints, blood vessels, and other parts of the body, which is most common in older persons. Phytic acid is a plant antioxidant (PMID: 3040709). Myo-inositol hexakisphosphate is a myo-inositol hexakisphosphate in which each hydroxy group of myo-inositol is monophosphorylated. It has a role as an iron chelator, an antineoplastic agent, a signalling molecule, an Escherichia coli metabolite, a mouse metabolite and a cofactor. It is a conjugate acid of a myo-inositol hexakisphosphate(12-). Phytic acid is under investigation in clinical trial NCT01000233 (Value of Oral Phytate (InsP6) in the Prevention of Progression of the Cardiovascular Calcifications). Myo-inositol hexakisphosphate is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Phytic acid is a natural product found in Chloris gayana, Vachellia nilotica, and other organisms with data available. Myo-Inositol hexakisphosphate is a metabolite found in or produced by Saccharomyces cerevisiae. Complexing agent for removal of traces of heavy metal ions. It acts also as a hypocalcemic agent.

Inositol 1,3,4-trisphosphate
Inositol 1,3,4-trisphosphate (CAS: 98102-63-7), also known as Ins(1,3,4)P3 or I3S, belongs to the class of organic compounds known as inositol phosphates.

myo-Inositol 1,3,4,5-tetrakisphosphate
myo-Inositol 1,3,4,5-tetrakisphosphate (CAS: 102850-29-3), also known as IP4, is a second messenger responsible for mediating Ca2+ entry through the plasma membrane and mobilizing intracellular Ca2+ by acting synergistically with inositol 1,4,5-trisphosphate (IP3). Inositol 1,4,5-trisphosphate 3-kinase (IP3K, EC 2.7.1.127) phosphorylates IP3 into IP4. Evidence shows that IP4 can activate a protein with ras- and rap-GAP activity and finally inactivate the G protein. This indicates that IP4 regulates Ca2+ influx in a GTP-dependent way, which potentially links the IP3 signalling pathway to GTP-regulated signalling mechanisms. IP4 is demonstrated to be a common regulator in Ca2+ homeostasis. IP4 can bind with a high affinity to several intracellular proteins: synaptotagmin (I and II), Gap1, Btk, and centaurin-alpha and may interact with synaptotagmin to inhibit synaptic transmission. IP4 also acts as a mediator in neuronal death in the ischemic hippocampus. IP4 production is not always associated with a modification in calcium concentration, and control of calcium mobilization is not the sole function proposed for IP4. IP4 defines an essential signalling pathway for T cell precursor responsiveness and development. In the thymus, IP4 is essential during the positive and negative selection of double-positive thymocytes, and in the control of thymocyte reactivity to antigens. IP4 is also a substrate for type I inositol-1,4,5-trisphosphate 5-phosphatase, phosphatidylinositol 4,5-bisphosphate 5-phosphatase A, and skeletal muscle and kidney enriched inositol phosphatase (PMID: 15740635, 14517551).

myo-Inositol 1,4,5-trisphosphate
myo-Inositol 1,4,5-trisphosphate (CAS: 20298-95-7), also known as Ins(1,4,5)P3 or InsP3, is an intracellular messenger formed by the action of phospholipase C on phosphatidylinositol 4,5-bisphosphate, which is one of the phospholipids that make up the cell membrane (PMID: 22453946). It is released into the cytoplasm where it releases calcium ions from internal stores within the cells endoplasmic reticulum. These calcium ions stimulate the activity of B kinase or calmodulin (PMID: 15189149). Its transient accumulation is due both to the enhanced metabolism via the Ca2+-calmodulin-sensitive Ins(1,4,5)P3 kinase, as well as a down-regulation of phosphatidylinositol 4,5-bisphosphate hydrolysis (PMID: 3041962). It is a major regulator of apoptotic signalling driving calcium (Ca2+) transients from the endoplasmic reticulum to mitochondria, thereby establishing a functional and physical link between these organelles. It also regulates autophagy through the interaction with Beclin 1 complex, and in particular, its inhibition/depletion strongly induces macroautophagy (PMID: 19325567). In addition, recent evidence suggests that the penetrating sperm delivers into mammalian eggs a novel isoform of phospholipase C (PLC), which promotes the formation of inositol 1,4,5-trisphosphate (PMID: 15362223). Intracellular messenger formed by the action of phospholipase C on phosphatidylinositol 4,5-bisphosphate, which is one of the phospholipids that make up the cell membrane.

Phosphatidylinositol-3,4,5-trisphosphate
Phosphatidylinositol (3,4,5)-trisphosphate (PtdIns(3,4,5)P3) commonly abbreviated to PIP3 is the product of the class I phosphoinositide 3-kinases (PI 3-kinases) activity on phosphatidylinositol (4,5)-bisphosphate. PtdIns(3,4,5)P3 is dephophosphorylated by the phosphatase, PTEN on the 3 position and by SHIPs (SH2-containing inositol phosphatase) on the 5 position of the inositol ring.
.The PH domain in a number of proteins binds to PtdIns(3,4,5)P3. Such proteins include Akt/PKB, PDK1, Btk1 and ARNO. The generation of PtdIns(3,4,5)P3 at the plasma membrane upon the activation of class I PI 3-kinases causes these proteins to translocate to the plasma membrane and accordingly affects their activity. The PH domain allows binding between PtdIns(3,4,5)P3 and G-protein coupled receptor kinases (GRKs). This enhances the binding of the GRK to the plasma membrane. (Wikipedia)

D-myo-inositol (1,2,4,5,6)-pentakisphosphate
D-myo-inositol (1,2,4,5,6)-pentakisphosphate is a member of the class of compounds known as inositol phosphates. Inositol phosphates are compounds containing a phosphate group attached to an inositol (or cyclohexanehexol) moiety. D-myo-inositol (1,2,4,5,6)-pentakisphosphate is soluble (in water) and an extremely strong acidic compound (based on its pKa). D-myo-inositol (1,2,4,5,6)-pentakisphosphate can be found in a number of food items such as cardoon, ucuhuba, common wheat, and burbot, which makes D-myo-inositol (1,2,4,5,6)-pentakisphosphate a potential biomarker for the consumption of these food products.
D-myo-inositol (1,2,6) trisphosphate
D-myo-inositol (1,2,6) trisphosphate is soluble (in water) and an extremely strong acidic compound (based on its pKa). D-myo-inositol (1,2,6) trisphosphate can be found in a number of food items such as biscuit, angelica, rice, and sapodilla, which makes D-myo-inositol (1,2,6) trisphosphate a potential biomarker for the consumption of these food products.
D-myo-inositol (1,3,4)-trisphosphate
D-myo-inositol (1,3,4)-trisphosphate, also known as ins(1,3,4)p3 or inositol 1,3,4-trisphosphoric acid, is a member of the class of compounds known as inositol phosphates. Inositol phosphates are compounds containing a phosphate group attached to an inositol (or cyclohexanehexol) moiety. D-myo-inositol (1,3,4)-trisphosphate is soluble (in water) and an extremely strong acidic compound (based on its pKa). D-myo-inositol (1,3,4)-trisphosphate can be found in a number of food items such as vanilla, hyacinth bean, japanese pumpkin, and green bean, which makes D-myo-inositol (1,3,4)-trisphosphate a potential biomarker for the consumption of these food products.
D-myo-inositol (1,4,5)-trisphosphate
D-myo-inositol (1,4,5)-trisphosphate is a member of the class of compounds known as inositol phosphates. Inositol phosphates are compounds containing a phosphate group attached to an inositol (or cyclohexanehexol) moiety. D-myo-inositol (1,4,5)-trisphosphate is soluble (in water) and an extremely strong acidic compound (based on its pKa). D-myo-inositol (1,4,5)-trisphosphate can be found in a number of food items such as ginkgo nuts, linden, swamp cabbage, and eggplant, which makes D-myo-inositol (1,4,5)-trisphosphate a potential biomarker for the consumption of these food products.
D-myo-inositol (2,3,4) trisphosphate
D-myo-inositol (2,3,4) trisphosphate is soluble (in water) and an extremely strong acidic compound (based on its pKa).
