C22 dihydro 1-Deoxyceramide (m18:0/22:0) is a very long-chain atypical ceramide containing a 1-deoxysphinganine backbone. 1-Deoxysphingolipids are formed when serine palmitoyltransferase condenses palmitoyl-CoA with alanine instead of serine during sphingolipid synthesis.1,2 C22 dihydro 1-Deoxyceramide (m18:0/22:0) has been found in mouse embryonic fibroblasts (MEFs) following application of 1-deoxysphinganine alkyne or 1-deoxysphinganine-d3.3 It has also been found as the most prevalent dihydro deoxyceramide species in mouse brain, spinal cord, and sciatic nerve at one, three, and six months of age.4 |1.
