Effect of processing parameters on sunflower phosphatidylcholine-enriched fractions extracted with aqueous ethanol
(Wiley VCH Verlag, 2009-10)
Lecithins are widely used in the food industry because of their multifunctional characteristics. Fractionation of the original mixture of phospholipids in lecithin is desirable for certain applications. The influence of ...
Interaction of hydroxy-xanthones with phosphatidylcholines: The effector decreases compressibility and increases the fluidity of membranes
(Elsevier Science, 2020-09)
This work reports the effect of hydroxy-xanthones (XAs) on 1,2-Dipalmitoyl-sn-glycero-3-phosphocholine(DPPC) and 1,2-Dimyristoyl-sn-glycero-3-phosphocholine (DMPC) bilayers as determined by ultrasound velocimetry,densimetry ...
Flunitrazepam-membrane non-specific binding and unbinding: Two pathways with different energy barriers
(Elsevier Science, 2002-02-19)
The effect of molecular packing on flunitrazepam's ability to interact with bio-membranes was studied using dipalmitoylphosphatidylcholine monomolecular layers at the air-water interface as a model membrane. Flunitrazepam ...
A kinetic study of phospholipids extraction by degumming process in sunflower seed oil
(Springer, 2000-12)
During the refining process of vegetable oils (degumming), phospholipids are eliminated by thermal treatment with water (hydratable phospholipids, HP) and other degumming agents such as phosphoric acid, citric acid, or ...
Characterization of a novel thermostable enzyme from thermus sp. 2.9 with phospholipase and acyltransferase activities
(Karger, 2019-01)
Phospholipases are classified in different enzyme families according to the ester bond they cleave within phospholipids. The use of phospholipases in industrial processes has prompted the search for new enzymes with ...
Computational predictions on the interactions of parabens with a dipalmitoyl phosphatidylcholine lipid bilayer and the human serum albumin protein
(Open Access Text, 2016-09)
Parabens are esters of para-hydroxybenzoic acid extensively used as preservatives in cosmetics and pharmaceutics. In the recent years their safe use has been questioned, mainly due to their estrogenic activity, their ...
A certain proportion of docosahexaenoic acid tends to revert structural and dynamical effects of cholesterol on lipid membranes
(Elsevier Science, 2021-06-01)
This work investigates how docosahexaenoic acid (DHA) modifies the effect of Cholesterol (Chol) on the structural and dynamical properties of dipalmitoylphosphatidylcholine (DPPC) membrane. We employ low-cost and non-invasive ...
Coexistence of phosphatidylcholine-specific phospholipase C and phospholipase D activities in rat cerebral cortex synaptosomes
(Springer Heidelberg, 2006-03)
DAG derived from phosphatidylcholine (PtdCho) acts as a lipid second messenger. It can be generated by the activation of phospholipase D (PLD) and the phosphatidic acid phosphohydrolase type 2 (PAP2) pathway or by a ...
Hydrophobic silver nanoparticles interacting with phospholipids and stratum corneum mimic membranes in Langmuir monolayers
(Academic Press Inc Elsevier Science, 2019-05)
The interaction of hydrophobic silver nanoparticles with different phospholipids and stratum corneum mimic (SCM) membranes is studied in Langmuir monolayers. Thus, silver nanoparticles coated with oleic acid (AgNP-OA) were ...
Selective localization of phosphatidylcholine-derived signaling in detergent-resistant membranes from synaptic endings
(Elsevier Science, 2010-03)
Detergent-resistant membranes (DRMs) are a class of specialized microdomains that compartmentalize several signal transduction processes. In this work, DRMs were isolated from cerebral cortex synaptic endings (Syn) on the ...
