1,2-DIPALMITOYL-SN-글리세롤 C화학적 특성, 용도, 생산

용도

1,2-Dipalmitoyl-sn-glycerol (1,2-DPG) is an analog of the protein kinase C (PKC)-activating second messenger diacylglycerol. 1,2-Dipalmitoyl-sn-glycerol is a weak activator of PKC.

정의

ChEBI: A 1,2-diacyl-sn-glycerol in which both acyl groups are specified as palmitoyl (hexadecanoyl).

일반 설명

In biochemical signaling, diacylglycerol (DAG) functions as a second messenger signaling lipid, and is a product of the hydrolysis of the phospholipid PIP2 (phosphatidylinositolbisphosphate) by the enzyme phospholipase C (PLC) (a membrane-bound enzyme) that, through the same reaction, produces inositol trisphosphate (IP3). Although inositol trisphosphate (IP3) diffuses into the cytosol, DAG remains within the plasma membrane due to its hydrophobic properties. IP3 stimulates the release of calcium ions from the smooth endoplasmic reticulum, whereas DAG is a physiological activator of protein kinase C (PKC). The production of DAG in the membrane facilitates translocation of PKC from the cytosol to the plasma membrane.
Diacylglycerol mimicks the effects of the tumor-promoting compounds phorbol esters.

Purification Methods

Crystallise S(-)-1,2-dipalmitin from chloroform/pet ether (b 40-60o) ~1:1.5. [S(-)-isomer: Baer & Kates J Am Chem Soc 72 942 1950, Hanahan & Vercamer J Am Chem Soc 7 6 1804 1954, R(+)-isomer: Tattrie et al. Arch Biochem 78 319 1958, Beilstein 2 IV 1173.] The racemate [40290-32-2] is polymorphic with different IR spectra. When crystallised from hexane, or other solvents, the higher melting form with m 71.5-72.5o is obtained. The melt then solidifies to give the lower melting -form with m 49.7-50o. The -form has m 61o (65-66o is also reported). When the lower melting forms are kept at their melting temperatures for a while, they are converted to the higher melting form.
