Phospholipids (PLs) are important biologically active substances in the human body and the storage form of information molecule precursors. Its hydrolyzed and oxidized products regulate human metabolism and improve memory by affecting the secretion system or the nervous system. It is also a chemical medium for the formation of many diseases. In addition, many diseases are related to abnormal PL metabolisms, such as diabetes, Alzheimer's disease, and pancreatic cancer. CD BioGlyco provides PL analysis services by high-performance liquid chromatography (HPLC), which has the characteristics of fast analysis speed and high resolution.
PLs refer to lipids containing phosphoric acid. PL molecules often exist in a combined state with proteins, cholesterol, glycolipids, and other substances, and are widely distributed in animal and plant tissues and microorganisms. They are the basic components of the biological membrane. PLs are amphiphilic molecules, which contain both a hydrophobic tail composed of fatty acid (FA) chains and a hydrophilic head composed of substituent groups linked to phosphoric acid. According to the main chain structure of the PLs, it is divided into phosphoglycerides and sphingomyelin.

PLs not only maintain the normal morphology of cell membranes but also participate in a large number of life activities of organisms. PLs play an important role in signal transduction, material exchange, cell apoptosis, and proliferation. PLs have good emulsifying, wetting, and dispersing effects, and are widely used in food, medicine, cosmetics, and other industries. PLs, as a food additive, improve the stability of food during processing. Refined PLs are added to cosmetics to improve skin condition and smooth damaged hair. The addition of PLs to livestock or aquafeeds promotes their growth. PLs are also commonly used materials in injection emulsions, which prepare drug complexes and improve the availability of drugs.

There are many unsaturated bonds in PLs of biological samples, which are easily decomposed by heat and are easily oxidized in the air. Therefore, HPLC is the most suitable chromatographic method for separating PLs. At CD BioGlyco, the PL analysis services we provide include:
