Description

3-Dehydrosphinganine is an intermediate in sphingolipid metabolism pathway. 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). Sphingolipid long chain bases (LCBs) - dihydrosphingosine (DHS) and phytosphingosine (PHS) - are implicated as secondary messengers in vital signaling pathways. [Biocyc SPHINGOLIPID-SYN-PWY]
