High Performance Liquid Chromatography (HPLC) Method for Analysis of Phosphoserine
Phosphoserine is a phosphorylated derivative of the amino acid serine, formed when a phosphate group is attached to its hydroxyl group. It plays a key role in cellular signaling and metabolic processes, serving as a precursor for the biosynthesis of important biomolecules like phospholipids, proteins, and nucleotides. Phosphoserine is also involved in protein phosphorylation, a critical post-translational modification regulating enzyme activity and signal transduction pathways.
Phosphoserine can be retained, separated and analyzed using a Primesep B mixed-mode stationary phase column. The analysis employs an isocratic method with a simple mobile phase comprising water, acetonitrile (MeCN), and phosphoric acid as a buffer. This method allows for detection using UV 200 nm.
