WebSphingosine-1-phosphate is an autocrinic and paracrinic regulator with intracellular and extracellular effects. Within a cell, it antagonizes ceramide-mediated effects, acts as a mitogen and inhibits apoptosis, and regulates calcium ion homeostasis and cell growth. Sphingolipids and Gangliosides, Fig. 2 Selected lysosphingolipids. WebJun 19, 2024 · From sphingoid bases, a variety of structures can be formed. For example, sphingosine-1-phosphate is produced through the phosphorylation of sphingosine, while its acylation results in ceramide structures, which is the base of many sphingolipids found in different organisms [].In this context, ceramides are composed of a fatty acid chain linked …

WebAug 12, 2011 · Box 1 illustrates the formation of C 16-dihydroceramide with a C 18-sphingoid backbone (18C 16 dhCer). Likewise, each of the other boxes illustrates the combinatorial action of unique enzymes/subunits to effect the formation of unique ceramides and subsequent sphingolipids. WebAug 2, 2024 · Sphingolipids are a class of lipids that are characterized by a long-chain amino alcohol (sphingoid) backbone with an amide-bound fatty acyl chain ( Heaver et al., 2024 ). Their structural diversity generates 1,000 of unique sphingolipids via the combination of various lipid headgroup and fatty acyl chains ( Sud et al., 2007 ). WebNov 8, 2024 · The sphingoid base backbone is synthesized from a long-chain fatty acyl-CoA and serine.
