General description

16:0-d31 SM or N-palmitoyl-d31-D-erythro-sphingosylphosphorylcholine is a deuterium labeled N-palmitoyl-sphingomyelin (SM). N-palmitoyl-SM is a sphingomyelin containing N-linked acyl chain with 16C atoms. Sphingomyelin is found in the outer leaflet of the mammalian cell membrane. It is a vital structural constituent of neurons and lipid bilayers.


16:0-d31 SM or N-palmitoyl-d31-D-erythro-sphingosylphosphorylcholine has been used as an internal standard in mass spectrometry to quantify lipids in biological samples.

The objectives were to determine the optimal feeding amount of choline in a ruminally protected form to reduce the triacylglycerol (TAG) concentration in liver and to increase TAG in blood plasma of dairy cows. Pregnant, nonlactating multiparous Holstein cows (n

Selectively deuterated N-palmitoyl sphingomyelins were studied by deuterium nuclear magnetic resonance spectroscopy ((2)H-NMR) to elucidate the backbone conformation as well as the interaction of the sphingolipids with glycerophospholipids. Macroscopic alignment of the lipid bilayers provided good spectral resolution and permitted
