Sphinganine (d18:0) is a precursor of ceramide and sphingosine as well as a substrate of sphingosine kinases, which generate sphinganine-1-phosphate. Sphinganine levels increase significantly in response to certain mycotoxins, including fumonisins, as well as in some cancers. Sphinganine can block protein kinase C...

Sphingosine is an amino alcohol most commonly characterized by an 18-carbon unsaturated hydrocarbon chain sphingosine (d18:1) (Cay-10007907). However, the hydrocarbon chain length of sphingosine, and the related dihydrosphingosine, can vary from 12-26 carbons in mammalian tissues. Sphingosine (d17:1) is a...

Human prostaglandin F synthase (PGFS) is a ~37 kDa monomeric protein with high sequence similarity to aldo-keto reductase family members. It exhibits two related primary activities, catalyzing the isomerization of PGH2 to PGF2alpha (PGH2 9,11-endoperoxide reductase activity), as well as the formation of...

2-Arachidonoyl glycerol (2-AG) is an endogenous agonist of the central cannabinoid (CB1) receptor. It is present at relatively high levels in the central nervous system and is the most abundant molecular species of monoacylglycerol found in rat brain. Monoacylglycerol lipase (MAGL) hydrolyzes 2-AG to arachidonic...
