Abstract:
Phospholipids that occur predominantly in the plasma membrane of mammalian cells are phosphatidylcholine (PC), phosphatidylserine (PS), phosphatidylethanolamine (PE), sphingomyelin (SM), and phosphatidylinositol (or phosphoinositide; PI). These membrane phospholipids are a promising source of disease-related biomarkers. Phospholipids and their metabolites are altered by the type of disease or disease progression. Metabolomics has shown that increased or decreased levels of altered phospholipids and their metabolites can be useful indicators for the diagnosis of various human diseases. In this review, we discuss the utility of the five major membrane phospholipids (PC, PS, PE, and SM, and PI) and their metabolites as diagnostic biomarkers of human diseases.

Blood Studies for Cardiovascular System III: Serum Lipid Profile
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
Membrane Lipids
Phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, and sphingomyelin are the most common phospholipids present in mammalian membranes. At physiological pH, phosphatidylserine is negatively charged, while the other three...
Overview of Fatty Acid Metabolism
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...
