Uses
C24:1 Dihydroceramide has been used as a standard in quadrupole time-of-flight (Q-TOF) mass spectrometry for the measurement of sphingolipid metabolites in adipose tissue. It has also been used a standard in diacylglycerol kinase (DGK) assay to quantify dihydroceramides in CLN9-deficient cells.
Definition
ChEBI: N-[(15Z)-tetracosenoyl]sphinganine is a dihydroceramide in which the ceramide N-acyl group is specified as (15Z)-tetracosenoyl (nervonoyl). It has a role as a mouse metabolite. It is a C24:1-sphinganine and a Cer(d42:1). It is functionally related to a (15Z)-tetracosenoic acid.
Biological Activity
C24:1 Dihydroceramide is a synthetic dihydroceramide. Dihydroceramides are reduced to ceramides by the enzyme dihydroceramide desaturase. Elevated levels of serum 24:1 DHC has been observed in patients with history of hepatocellular carcinoma (HCC) pre-orthopic liver transplantation (OLT), compared to patients with no prior HCC. Therefore, 24:1 DHC can be used as a HCC biomarker in post-OLT patients.
