别名

1-hexanoyl-sn-glycero-3-phosphate (ammonium salt); PA(6:0/0:0)

测定

>99% (LPA; may contain up to 10% of the 2-LPA isomer, TLC)

一般描述

Lysophosphatidic acid (LPA) belongs to a class of phospholipids, that has a glycerol backbone attached by a phosphate group, an aliphatic chain and a hydroxyl group. It has a phosphate group attached to sn-3 position, an aliphatic chain attached to sn-1 or sn-2 position and the hydroxyl group attached to the remaining sn-1 or sn-2 position. 06:0 Lyso PA/HHGP, belongs to the LPA (lysophosphatidic acid) family. It is a negatively charged single chain lipid. Lysophosphatidic acid (LPA) has a free hydroxyl and phosphate moiety. It is hydrophilic and is not associated with the membrane. It is the major constituent of serum.

应用

06:0 Lyso PA (LPA) has been used in the structure-activity relationship (SAR) analysis with G-protein receptor GPR92. It has also been used in lipid assay in the treatment of serum-starved primary mouse embryonic fibroblast cells. 06:0 Lyso PA has been used to study the role of lipid binding to MxiM protein in co‐crystallization experiments.

生化/生理作用

Lysophosphatidic acid (LPA) is the precursor for the synthesis of phospholipids in eukaryotes and prokaryotes. It acts as an intercellular signaling molecule. Activated platelets produce LPA. It plays a major role in tissue healing and wound regeneration. LPA binds to G-protein coupled receptors. It possesses mitogenic properties. LPA inhibits differentiation of neuroblastoma and myoblast, aids in neurotransmitter release and smooth muscle contraction. It is a potential biomarker for ovarian and gynecological cancers. It is implicated in the initiation of neuropathic pain. Lysophosphatidic acid (LPA) participates in several biological functions. LPA stimulates platelet aggregation, chemotaxis, cytoskeleton rearrangement, Ca2+ mobilization and cell proliferation. 06:0 Lyso PA/HHGP possesses a micromolar binding affinity for global regulator of LEE (locus of enterocyte effacement) repressor (GrlR) and for β-lactoglobulin.
