    Product Description

    C16 dihydro Ceramide-d9 (d18:0/16:0-d9) is intended for use as an internal standard for the quantification of C16 dihydro ceramide (Item No. 24369) by GC- or LC-MS. C16 dihydro Ceramide is a bioactive sphingolipid and precursor in the de novo synthesis of C16 ceramide (d18:0/16:0) (Item No. 10681) that lacks the 4,5-trans double bond.1 C16 dihydro Ceramide (46 nM) inhibits C16 ceramide-induced membrane permeabilization, measured as cytochrome c oxidation, in rat liver mitochondria in a concentration-dependent manner. It also inhibits C16 ceramide-induced channel formation in liposomes. C16 dihydro ceramide is biologically inactive as a single agent, lacking the ability to induce apoptosis, cytochrome c release, or channel formation in phospholipid membranes in the absence of C16 ceramide.

    WARNING This product is not for human or veterinary use.
