The present work aims to systematically demonstrate the authenticity of honeys with non-extractable proteins for the first time, by means of EA-IRMS and LC-IRMS. Fifty-three pure honeys of various botanical and geographical origins were studied and a criterion on the

Phosphorus-31 nuclear magnetic resonance (31P NMR) is used to investigate acid-labile phosphorylation of histone H4. 31P NMR detects phosphorylated histidine residues in in vitro enzymatically phosphorylated H4. The source of kinase is nuclei from either regenerating rat liver or Walker-256

In order to study the lipid composition of human white matter, we have developed a 31P NMR spectroscopy method, which allows the determination and quantitation of the main phospholipids found in biological membranes. The technique is based upon the use
