It is the enzymatic oxidation product of 4-hydroxysphinganine. Sphingolipids are essential components of the plasma membrane in all eukaryotic cells. S. cerevisiae cells make three complex sphingolipids: inositol-phosphoceramide (IPC), mannose-inositol-phosphoceramide (MIPC), and mannosyl-diinositol-phosphorylceramide (M(IP)2C) [ Dickson02 ]. In the yeast plasma membrane sphingolipids concentrate with ergosterol to form lipid rafts, specialized membrane microdomains implicated in a variety of cellular processes, including sorting of membrane proteins and lipids, as well as organizing and regulating signaling cascades [ Bagnat02 ]. Intermediates in sphingolipid biosynthesis have been shown to play important roles as signaling molecules and growth regulators. Sphingolipid long chain bases (LCBs), dihydrosphingosine (DHS) and phytosphingosine (PHS), have been implicated as secondary messengers in signaling pathways that regulate heat stress response. Other intermediates, phytoceramide and long-chain base phosphates (LCBPs), have been shown to be components of tightly-controlled ceramide/LCBP rheostat, which regulates cell growth. Since phosphoinositol-containing sphingolipids are unique to fungi, the sphingolipid biosynthesis pathway is considered a target for antifungal drugs [HMDB] PHS-1-ate PHS-1-Phosphate Phytosphingosine-1-P C18H40NO6P 397.4871 397.259324529 {[(2R,3R,4R)-2-amino-3,4-dihydroxyoctadecyl]oxy}phosphonic acid [(2R,3R,4R)-2-amino-3,4-dihydroxyoctadecyl]oxyphosphonic acid 7664-38-2 CCCCCCCCCCCCCC[C@@H](O)[C@H](O)[C@H](N)COP(O)(O)=O InChI=1S/C18H40NO6P/c1-2-3-4-5-6-7-8-9-10-11-12-13-14-17(20)18(21)16(19)15-25-26(22,23)24/h16-18,20-21H,2-15,19H2,1H3,(H2,22,23,24)/t16-,17-,18-/m1/s1 AYGOSKULTISFCW-KZNAEPCWSA-N belongs to the class of organic compounds known as phosphosphingolipids. These are sphingolipids with a structure based on a sphingoid base that is attached to a phosphate head group. They differ from phosphonospingolipids which have a phosphonate head group.
