The water-soluble phosphate profiles determined by 31P nuclear magnetic resonance (NMR) of a broad range of vertebrate lenses are presented. We identify threonine ethanolamine phosphodiester (TEP) in intact lenses and lens extracts by its chemical shift and its physical and chemical characteristics. Amongst the species studied, we give the first characterization of frog lens where not only serine ethanolamine phosphodiesters (SEP) but TEP are found.
