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 ...

Separation and identification of ceramides derived from human plasma sphingomyelins

open access: yes, 1969
Sphingomyelins from human blood plasma have been converted into ceramides by enzymatic hydrolysis with phospholipase C. After acetylation the ceramides were fractionated by thin-layer chromatography on silica gel containing silver nitrate.

Low serum sphingolipids in children with attention deficit-hyperactivity disorder

open access: yesFrontiers in Neuroscience, 2015
Background: Attention deficit-hyperactivity disorder (ADHD) is the most prevalent neuropsychiatric condition in childhood. ADHD is a multifactorial trait with a strong genetic component. One neurodevelopmental hypothesis is that ADHD is associated with a

RGDfV increases ceramides and decreases sphingomyelins, and these changes are abrogated following ASM. knockdown.

open access: yes, 2013
Lysates of cells treated with siRNA and RGDfV as in Figs. 2C–D as were analyzed by mass spectrometry as detailed in Methods. Sphingolipid nomenclature: Ceramides are 1,3-hydroxy-2-amino alkanes (sphinganine) or alkenes (sphingosine) with fatty acid alkyl

Reliability of Serum Metabolites over a Two-Year Period: A Targeted Metabolomic Approach in Fasting and Non-Fasting Samples from EPIC.

open access: yesPLoS ONE, 2015
ObjectiveAlthough metabolic profiles have been associated with chronic disease risk, lack of temporal stability of metabolite levels could limit their use in epidemiological investigations.

Interaction of Cholesterol with Sphingomyelins and Acyl-Chain-Matched Phosphatidylcholines: A Comparative Study of the Effect of the Chain Length [PDF]

open access: yes, 1999
In this study we have synthesized sphingomyelins (SM) and phosphatidylcholines (PC) with amide-linked or sn-2 linked acyl chains with lengths from 14 to 24 carbons.

Circulating sphingolipids and subclinical brain pathology: the cardiovascular health study

open access: yesFrontiers in Neurology
BackgroundSphingolipids are implicated in neurodegeneration and neuroinflammation. We assessed the potential role of circulating ceramides and sphingomyelins in subclinical brain pathology by investigating their association with brain magnetic resonance ...

Degradation of fluorescent and radiolabelled sphingomyelins in intact cells by a non-lysosomal pathway

open access: yes, 1995
International audienceThe aim of the present study was to investigate the role of the entitled neutral, sphingomyelinase in the non-lysosomal pathway of sphingomyelin degradation by intact cells (Spence et al. (1983) J. Biol. Chem. 258, 8595-8600; Levade

Altered levels of acylcarnitines, phosphatidylcholines, and sphingomyelins in peritoneal fluid from ovarian endometriosis patients.

open access: yes, 2016
Endometriosis is a complex, polygenic, and estrogen-dependent disease that affects 6% to 10% of women of reproductive age, and 30% to 50% of women with infertility and/or pelvic pain.
