Sphingolipids and their metabolism in physiology and disease

WebSphingosines are a group of related long-chain aliphatic 2-amino-1,3-diols (long-chain bases-LCBs). Sphingosine (4-sphingenin; 2-D-amino-4-octadecene-1,3 diol) occurs most frequently in animal glycolipids. Others that are often found in glycolipids include dihydrosphingosine (sphinganine) and 4-eicosphingenine (C20). WebNov 8, 2024 · Sphingolipids The hydrophobic tails of sphingolipids are made up of a fatty acid and a long carbon chain on the sphingoid base. The name of the lipid is thus a combination of the name of the sphingoid base and the fatty acid (Figure 1.3. 2 C) (Fahy et al 2011).
