title: Use of N-([1-14C]hexanoyl)-D-erythro-sphingolipids to assay sphingolipid metabolism.
abstract: An advantage of using N-([1-14C]hexanoyl)sphingolipids to assay sphingolipid metabolism is their ability to rapidly and spontaneously transfer into biological membranes without destroying membrane integrity. This property allows analysis of the activity of enzymes of sphingolipid metabolism under conditions in which the rate of product formation is not limited by availability of substrate, as is often the case with naturally occurring lipids whose rates of spontaneous transfer are extremely slow. Thus, the use of N-([1-14C]hexanoyl)sphingolipids provides an alternative means for studying sphingolipid metabolism in vitro.
