Sphingosine (d20:1)

一般描述

Sphingosine (d20:1), also known as icosasphingosine, is a synthetic sphingosine with 20 carbon long chain bases (LCB). It is directly produced by the sphingolipid de novo synthesis pathway and not by hydrolysis of complex sphingolipids. In higher animals, it is one of the most abundant sphingoid bases of gangliosides.

应用

Sphingosine (d20:1) has been used as a reference substance in liquid chromatography/tandem mass spectrometry analysis to quantitatively analyze sphingolipids with C20- long chain bases in human central nervous tissue.

生化/生理作用

Sphingosine (d20:1) or C20-sphingosine acts as an intermediate in the synthesis of ceramides, which are vital components of mammalian epidermis. It may be involved in regulation of epidermal differentiation. C20 long chain bases-containing sphingolipids might exhibit detrimental effect on protein homeostasis and neural functions.
