Phospholipid signaling

open access: yesCell, 1995
Ten years ago, describing what is new in phospholipid signaling in ten pages of Cell would have been easy; it would have been essentially a summary of the phospho-inositidase C (PIC) story: phosphatidylinositol(4,5)bisphos-phate (Ptdlns(4,5)P2) hydrolysis to inositiol(1,4,5)trisphos-phate (Ins(1",4,5)P3), with the synergistic action of Ca 2÷(mobilized ...

Determination of Phospholipids in Antarctic Krill by Hydrophilic Interaction Ultra-high Performance Liquid Chromatography-Tandem Mass Spectrometry Using TiO2/KCC-1 Solid Phase Extraction [PDF]

open access: yesShipin Kexue
Phosphatidylcholine (PC), phosphatidyl ethanolamine (PE), phosphatidylserine (PS), and phosphatidylinositol (PI) are the four major phospholipids in Antarctic krill.

Research Advances in Regulatory Effect of Phospholipids on Meat Quality [PDF]

open access: yesShipin Kexue
Phospholipids, a class of polar lipids with complex structure and multiple functions, are composed of glycerophospholipids and sphingomyelins. As an important component of cell membranes, phospholipids are involved in many physiological activities, such ...

Substrate-Specific Inhibition Constants for Phospholipase A2 Acting on Unique Phospholipid Substrates in Mixed Micelles and Membranes Using Lipidomics. [PDF]

open access: yes, 2019
Assaying lipolytic enzymes is extremely challenging because they act on water-insoluble lipid substrates, which are normally components of micelles, vesicles, and cellular membranes.

A minimal biochemical route towards de novo formation of synthetic phospholipid membranes. [PDF]

open access: yes, 2019
All living cells consist of membrane compartments, which are mainly composed of phospholipids. Phospholipid synthesis is catalyzed by membrane-bound enzymes, which themselves require pre-existing membranes for function.

Effect of dipolar-angle on phospholipid assembly [PDF]

open access: yesPhys. Rev. E 95, 062703 (2017), 2016
We report the effect of lipid head-group dipole orientation on phase behaviour of phospholipid assembly. The work explains molecular-scale mechanism of ion-lipid, anesthetic-lipid interactions where reorientation of dipoles play important role in membrane potential modification. Molecular Dynamics simulations are performed to analyse structure-property

Three-year tracking of fatty acid composition of plasma phospholipids in healthy children [PDF]

open access: yes, 2007
Objectives: The fatty acid composition of plasma phospholipids reflects the dietary fatty acid intake as well as endogenous turnover. We aimed at investigating the potential tracking of plasma phospholipid fatty acid composition in children that ...

Opsin Is a Phospholipid Flippase [PDF]

open access: yesCurrent Biology, 2011
Polar lipids must flip-flop rapidly across biological membranes to sustain cellular life [1, 2], but flipping is energetically costly [3] and its intrinsic rate is low. To overcome this problem, cells have membrane proteins that function as lipid transporters (flippases) to accelerate flipping to a physiologically relevant rate.

A mesoscale model for quantitative phospholipid monolayer simulations at the air-water interface [PDF]

open access: yesarXiv, 2021
A mesoscale model with molecular resolutions is presented for the dipalmitoyl-phosphatidylcholine (DPPC) and 1-palmitoyl-2-oleyl-sn-glycero-3-phosphocholine (POPC) monolayer simulations at the air-water interface using many-body dissipative particle dynamics (MDPD).

Ice Formation in Model Biological Membranes in the Presence of Cryoprotectors [PDF]

open access: yesNuclear Instruments & Methods in Physics Research A 448 (2000) 225-260, 2001
Ice formation in model biological membranes is studied by SAXS and WAXS in the presence of cryoprotectors: dimethyl sulfoxide and glycerol. Three types of phospholipid membranes: DPPC, DMPC, DSPC are chosen for the investigation as well-studied model biological membranes. A special cryostat is used for sample cooling from 14.1C to -55.4C.
