Occurrence of free O-phosphoserine and O-phosphothreonine in porcine liver.
The occurrence of free O-phosphoserine and O-phosphothreonine in porcine liver is demonstrated. These amino acids were separated from the tissue extracts by anion- and cation-exchange chromatography and thin-layer chromatography, and were identified by gas chromatography with flame photometric detection and gas chromatography-mass spectrometry. The contents of O-phosphoserine and O-phosphothreonine in the liver were estimated to be 377 +/- 13 ng/g and 115 +/- 2 ng/g, respectively.
