| Hazard Information | Back Directory | [Description]
Dihydrosphingosine (764-22-7) is a biosynthetic precursor of sphingosine. Inhibitor of protein kinase C1?and phospholipases A2 and D2. | [Chemical Properties]
White Powder | [Uses]
Biosynthetic precursor of Sphingosine. Inhibits protein kinase C. | [Definition]
ChEBI: Sphinganine is a 2-aminooctadecane-1,3-diol having (2S,3R)-configuration. It has a role as an EC 2.7.11.13 (protein kinase C) inhibitor, a human metabolite and a mouse metabolite. It is a conjugate base of a sphinganine(1+). | [General Description]
Sphinganine (d18:0) is a substrate for the enzyme ceramide desaturase. It is synthesized indirectly due to the interconversion of supplemented glycine to serine. Sphinganine (d18:0) is catabolized to ceramide. | [Biochem/physiol Actions]
Sphinganine (d18:0) levels are not altered in hereditary sensory neuropathy type 1 cells. Accumulation of d18:0 is observed in tumor hypoxia. It is useful as a biomarker for studying microbial diversity. | [References]
