Application

L-α-Lysophosphatidylinositol sodium salt from Glycine max (soybean) has been used as an agonist of G protein-coupled receptor 55 (GPR55).

Biochem/physiol Actions

L-α-Lysophosphatidylinositols (LPI) functions as an endogenous ligand for putative cannabinoid receptor and G protein-coupled receptor 55 (GPR55). LPI plays a regulatory role in cell proliferation, migration and function. Increased circulatory levels of LPI has been observed in the obese patients. In addition, overexpression of LPI leads to the development of various types of cancers including ovarian and breast cancer. LPI can be used as a potential diagnostic and prognostic biomarker for ovarian cancer.
L-α-Lysophosphatidylinositols from Glycine max (soybean) are enriched with stearate and palmitate. Soybean Lysophosphatidylinositols may be compared with other lysophosphatidylinositol for biological activities which depend upon the identity of the acylated fatty acid.

Preparation Note

Prepared by the action of phospholipase A on L-α-phosphatidylinositol.

Analysis Note

Contains primarily palmitic and stearic acids.

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. What is the molecular weight of L-α-Lysophosphatidylinositol sodium salt from Glycine max, Product L7635?

    We have calculated a value of 605.1, based on the structure of phosphatidyl-1-inositol and the assumption that the main fatty acids present as part of the structure are C16:0 (58%) and C18:0 and C18:2 (42%).

  4. What fatty acid groups does L-α-Lysophosphatidylinositol sodium salt from Glycine max, Product L7635, contain?

    The main fatty acid group is palmitic acid.  The next most abundant fatty acid groups tend to be stearic acid and linolenic acid, and then oleic acid and linoleic acid.
