Application
21:0 PC has been used as a standard in linearity experiment to evaluate linearity response of the most abundant lipid classes. 21:0 PC may be used as an internal standard for the quantification of phospholipids (PLs). It may also be used as a phospholipid standard for the analysis of dried lipid extracts of S. meliloti in the positive-ionization mode.
Biochem/physiol Actions
Phosphatidylcholine (PC) helps to block the penetrance of bacteria by acting as a surfactant in the mucus.
General description
Phosphatidylcholines (PCs) are phospholipids, that are ubiquitously present in the tissues of animals. The sn-1 and sn-2 position of PC has saturated and unsaturated fatty acids respectively. It can be produced through methylation pathway.
The list of Phosphatidylcholine products offered by Avanti is designed to provide compounds having a variety of physical properties. Products available include short chain (C3-C8 are water soluble and hygroscopic), saturated, multi-unsaturated and mixed acid PC′s. All of the products are purified by HPLC, and special precautions are taken to protect the products for oxidization and hydrolysis.

A shotgun lipidomics approach that allowed the analysis of eight lipid classes directly from crude extracts of the soil bacterium Sinorhizobium meliloti is presented. New MS-MS transitions are reported for the analysis of monomethylphosphatidylethanolamines, dimethylphosphatidylethanolamines, and three bacterial non-phosphorus-containing lipid
The effect of dietary fat content on phospholipid fatty acid profile is muscle fiber type dependent.

A high-saturated-fat diet (HFD) induces obesity and insulin resistance (IR). IR has been linked to alterations and increased saturation in the phospholipid composition of skeletal muscles. We aimed to determine whether HFD feeding affects fatty acid (FA) membrane profile in

High-throughput targeted lipid profiling with liquid chromatography-mass spectrometry (LC-MS) has been used extensively to identify associations between plasma lipid species and disease states. Such methods, used to characterize larger clinical cohorts, often suffer from an inability to differentiate isomeric forms
