Genetic variants including markers from the exome chip and metabolite traits of type 2 diabetes [PDF]

open access: yes, 2017
Diabetes-associated metabolites may aid the identification of new risk variants for type 2 diabetes. Using targeted metabolomics within a subsample of the German EPIC-Potsdam study (n = 2500), we tested previously published SNPs for their association ...

Probing the role of C-1 ester group in Naja naja phospholipase A2-phospholipid interactions using butanetriol-containing phosphatidylcholine analogues [PDF]

open access: yes, 1999
To understand the role of the ester moiety of the sn-1 acyl chain in phospholipase A2-glycerophospholipid interactions, we introduced an additional methylene residue between the glycerol C1 and C2 carbon atoms of phosphatidylcholines, and then studied ...

Non‐targeted metabolite profiling reveals biochemical diversity of three East Asian mosses

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Mosses are known for their bioactive composition and adaptation to environmental stresses. This study explores the metabolic diversity of three East Asian moss species, Niphotrichum japonicum, Calohypnum plumiforme, and Polytrichum formosum, using high‐resolution mass spectrometry. Lipids, particularly unsaturated fatty acids linked to cold adaptation,

Improved method for the synthesis of phosphatidylcholines.

open access: yesJournal of Lipid Research, 1984
An improved method for the synthesis of phosphatidylcholines from phosphatidic acid and choline is described. The technique utilizes the tetraphenylborate salt of choline together with the condensing agent 2,4,6-triisopropylbenzenesulfonyl chloride.

The contribution of extracellular RNA and its derived biomaterials in disease management

open access: yesBMEMat, EarlyView.
The implications of exRNA's biological function and the structural uniqueness of RNA help establish a close connection between RNA, material, and modern medicine. Abstract The RNA found in the circular system is known as extracellular RNA (exRNA). This kind of RNA has been found to play a biological role similar to that of a messenger. They can be used

Mass spectrometry of the phosphatidyl amino alcohols: detection of molecular species and use of low voltage spectra and metastable scanning in the elucidation of structure

open access: yesJournal of Lipid Research, 1972
The basic fragmentation mechanisms occurring in the mass spectra of the phosphatidylcholines have been described previously, and evidence was adduced to show that many of the more abundant ions are related by electron impact-induced processes.
