-description: '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 mannose-(inositol phosphate)2-ceramide
-  (M(IP)2C)(CITS: [12069845]).  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 (CITS: [12452424]).  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 (CITS: [9405471])(CITS: [11967828]).  Other
-  intermediates, phytoceramide and long-chain base phosphates (LCBPs), have been shown
-  to be components of the tightly-controlled ceramide/LCBP rheostat, which regulates
-  cell growth (CITS: [12684378]).  Since phosphoinositol-containing sphingolipids
-  are unique to fungi, the sphingolipid biosynthesis pathway is considered a target
-  for antifungal drugs (CITS: [9092515])(CITS: [15578972]).  SOURCE: SGD pathways,
