Densitometric Quantification of Ether-Type Phospholipids

HPTLC DENSITOMETRIC QUANTIFICATION OF SENNOSIDES FROM Cassia angustifolia

The use of medicinal herbs to relieve and treat diseases is increasing because of their mild features and few side effects (Basgel and Erdemoglu, 2006). These plants are unlicensed and freely available, however, and there is no requirement to demonstrate efficacy, safety or quality (Ernst, 1998). Cassia angustifolia Vahl (Family: Caesalpinaceae), popularly known as senna, is a valuable plant dr...

1. Methodology of lipidomics: Tandem mass spectrometry of ether phospholipids

Tandem mass spectrometry of intact lipids is a highly specialized technique. It has been widely used in structural elucidation of molecular species of various ether phospholipid subclasses. All marine animals contain abundant ether phospholipid species. Although a combination of liquid and gas chromatography is the time-consuming in providing such structural information of a common phospholipid...

Arachidonic acid mobilization among phospholipids in murine mastocytoma P-815 cells: role of ether-linked phospholipids.

The ethanolamine-containing glycerophospholipids, choline-containing glycerophospholipids, and phosphatidylinositol fractions are major sources of arachidonic acid in murine mastocytoma P-815 cloned cells. The choline-linked fraction contained high arachidonic acid contents in 1-O-alkyl-2-acyl- (18%) and 1,2-diacyl-sn-glycero-3-phosphocholine (11%), with smaller amounts in 1-O-alk-1'-enyl-2-acy...

Dictyostelium uses ether-linked inositol phospholipids for intracellular signalling.

Inositol phospholipids are critical regulators of membrane biology throughout eukaryotes. The general principle by which they perform these roles is conserved across species and involves binding of differentially phosphorylated inositol head groups to specific protein domains. This interaction serves to both recruit and regulate the activity of several different classes of protein which act on ...
