Sphingomyelins Prevent Propagation of Lipid Peroxidation—LC-MS/MS Evaluation of Inhibition Mechanisms

Molecules, 2020
Free radical driven lipid peroxidation is a chain reaction which can lead to oxidative degradation of biological membranes. Propagation vs. termination rates of peroxidation in biological membranes are determined by a variety of factors including fatty ...

Metabolomic Signature of Visceral Adiposity: Insights from a Population-Based Cohort [PDF]

Metabolites
Background: Visceral adipose tissue (VAT) is a key determinant of cardiometabolic risk, yet its underlying molecular mechanisms remain incompletely characterized.

Plasma lipids connecting olfaction with cognition and physical function [PDF]

Scientific Reports
Olfactory deficit is an early sign of neurodegenerative diseases, such as Alzheimer’s disease (AD), and is related to age-related cognitive and physical function decline. However, underlying biological processes are not fully understood.

Sphingomyelins and ceramides with VLCPUFAs are excluded from low-density raft-like domains in differentiating spermatogenic cells

Journal of Lipid Research, 2017
Rat spermatogenic cells contain sphingomyelins (SMs) and ceramides (Cers) with very long-chain PUFAs (VLCPUFAs) in nonhydroxylated (n-V) and 2-hydroxylated (h-V) forms. How these atypical species distribute among membrane fractions during differentiation

Presence of unsaturated sphingomyelins and changes in their composition during the life cycle of the moth Manduca sexta

Journal of Lipid Research, 2004
NMR and electrospray ionization tandem mass spectrometry were used to show for the first time the presence of sphingomyelins in extracts of the tobacco hornworm Manduca sexta (Lepidoptera).

Selective association of plasma sphingolipid species with insulin sensitivity and secretion in normoglycemic Black and White American adults [PDF]

Experimental Biology and Medicine
Ceramides and other sphingolipids are associated with diabetes risk. Here, we examined the association of plasma sphingolipids with insulin sensitivity and secretion in people without diabetes.

Nonalcoholic fatty liver disease stratification by liver lipidomics

Journal of Lipid Research, 2021
Nonalcoholic fatty liver disease (NAFLD) is a common metabolic dysfunction leading to hepatic steatosis. However, NAFLD's global impact on the liver lipidome is poorly understood.

Plasma ceramides containing saturated fatty acids are associated with risk of type 2 diabetes

Journal of Lipid Research, 2021
Recent studies suggest that the type of saturated fatty acid bound to sphingolipids influences the biological activity of those sphingolipids. However, it is unknown whether associations of sphingolipids with diabetes may differ by the identity of bound ...

Different Lipid Signature in Fibroblasts of Long-Chain Fatty Acid Oxidation Disorders

Cells, 2021
Long-chain fatty acid oxidation disorders (lc-FAOD) are a group of diseases affecting the degradation of long-chain fatty acids. In order to investigate the disease specific alterations of the cellular lipidome, we performed undirected lipidomics in ...

Improved quantitation of plasma lipids by direct gas-liquid chromatography

Journal of Lipid Research, 1969
A preliminary digestion of total plasma lipid extracts with phospholipase C, which converts the lysolecithins, lecithins, and sphingomyelins into monoglycerides, diglycerides, and ceramides, respectively, has been shown to facilitate subsequent ...
