Ceramide NS

ceramide ns, formerly known under the inci name ceramide 2, is the n-acylated sphingolipid consisting of sphingosine having the d-erythro structure linked to a normal saturated or unsaturated fatty acid. as opposed to the broader definition for ceramide 2 which includes sphingolipids consisting of either sphingosine or dihydrosphingosine (sphinganine), ceramide ns is limited to sphingosine-based ceramides.
