C18 dihydro Ceramide-d3 is intended for use as an internal standard for the quantification of C18 dihydro ceramide (d18:0/18:0) by GC- or LC-MS. C18 dihydro Ceramide is a bioactive sphingolipid and precursor in the de novo synthesis of C18 ceramide (d18:1/18:0) that lacks the 4,5-trans double bond.1 Increased C18 dihydro ceramide lipid levels lead to increased triacylglycerol storage and autophagosome accumulation as well as upregulation of the fibrosis markers α-SMA and FGF2 in Chang and LX-2 liver cells. C18 dihydro Ceramide is elevated in the plasma of pre-diabetics up to 9 years prior to the onset of type 2 diabetes.2 It is also elevated in the skin of patients with lesional atopic dermatitis.3
