Structure of plasma sphingadienine

Journal of Lipid Research, 1969
The dienic long-chain base (sphingadienine) of human plasma sphingomyelins has been identified as d-erythro-1,3-dihydroxy-2-amino-4-trans-14-cis-octadecadiene. A similar sphingosine was also detected in plasma sphingomyelins of rat, rabbit, and cat.

UHPLC-MS based metabolomics study of the ErZhi formula on skeletal muscle against osteosarcopenia focusing on energy metabolism. [PDF]

Animal Model Exp Med
ErZhi formula (EZF) is composed of Ligustri Lucidi Fructus (LLF) and Ecliptae herba (EH). Ovariectomized (OVX) and sham rats received 12‐week intragastric treatment with EZF, alendronate, and vehicle saline. Gastrocnemius tissues were harvested to systematically evaluate pharmacodynamic changes in skeletal muscle morphology, mitochondrial ...

Gas-chromatography/mass-spectrometry analysis of human skin constituents as heptafluorobutyrate derivatives with special reference to long-chain bases

Journal of Lipid Research, 2002
The composition of the constituents (monosaccharides, long-chain bases, and fatty acids) found in an ethanol extract of the human skin could be determined, without time-consuming steps of purification, after acid-catalyzed anhydrous methanolysis ...

Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.

Seed lipid profiles of perennial ryegrass: Global patterns and differentiation of ryegrass cultivars and Epichloë endophytes

Grassland Research, EarlyView.
Seed lipid profiles from three ryegrass cultivars infected with AR501 show distinct changes in the medium‐chain diacylglycerols, triacylglycerols and sphingolipids. The differential peal LN745.5052_5.78 can be identified as PG 16:0_18:2 with the supporting ms2 fragmentation spectrum. Abstract Background Forage perennial ryegrass (Lolium perenne L.) has

Effects of specific fatty acids on sphinganine ± GT-11-induced dihydroceramides and cytotoxicity.

, 2013
A, B) Effects on dihydroceramides. CCRF-CEM cells were treated with (A) sphinganine (1 µM), or (B) sphinganine (1 µM) + GT-11 (0.5 µM), and supplemented with the indicated fatty acids (5 µM) for six hours, followed by sphingolipid assay.

Early and late HIV-1 membrane fusion events are impaired by sphinganine lipidated peptides that target the fusion site

Biochemical Journal, 2014
Lipid-conjugated peptides have advanced the understanding of membrane protein functions and the roles of lipids in the membrane milieu. These lipopeptides modulate various biological systems such as viral fusion.
