The phospholipids content of Cyperus esculentus tubers were identified by both HPTLC and/or HPLC techniques. The identified phospholipid classes were Phosphatidic acids, Phosphatidylinositol, Phosphatidylethanolamines, Phosphatidylcholine, L-α Phosphatidyl DL-glycerol, Cardiolipin, and L-α-Lysophosphatidylcholine. The hydrolysis of total phospholipids showed that four fatty acids were attached ...

Activation of naïve T helper cells by presentation of cognate antigen initiates a complex intracellular signaling process leading to development of functionally active effector cell population. The switch from quiescent naïve state to activated state involves a profound change of cellular metabolism, required for completion of multiple rounds of proliferation. Using ultra performance liquid chr...

Activated platelets generate an eicosanoid proposed to be 8-hydroxy-9,10-dioxolane A3 (DXA3). Herein, we demonstrate that significant amounts of DXA3 are rapidly attached to phosphatidylethanolamine (PE) forming four esterified eicosanoids, 16:0p, 18:0p, 18:1p and 18:0a/DXA3-PEs that can activate neutrophil integrin expression. These lipids comprise the majority of DXA3 generated by platelets, ...

We have been developing the use of plasma-membrane-bound fluorescent probes to measure the pH values at the surfaces of living chondrocytes. For this purpose, three lipophilic pH indicators were made by covalently binding the xanthene dyes fluorescein, eosin or dichlorofluorescein to the amino group of phosphatidylethanolamine. The probes were incorporated into phospholipid vesicles and the eff...

We constructed a yeast stain, TKY12Ga, in which phosphatidylethanolamine (PE) synthesis can be controlled by means of the carbon source in the medium. When PE synthesis was blocked, its growth was inhibited. However, in the presence of exogenous didecanoyl PE (diC10PE), TKY12Ga grew despite an inability to synthesize PE. Our system, which employs TKY12Ga strain and diC10PE, provides a valuable ...
