Separation and characterization of the unknown phospholipid in human lens membranes.

Abstract

The ability to separate the unknown from sphingomyelin and the power of 1H NMR spectroscopy allowed the proposition of the identity of the major component of human lens membranes as 4,5-dihydrosphingomyelin. Although the synthetic compound is known to be involved in the formation of extended hydrogen-bonding networks, its biologic and physicochemical properties need further study.
