Sphingoglycolipids structure
WebFeb 1, 2004 · Sphingoglycolipids (SGLs) are cell membrane constituents. As the ceramide structure influences the biological properties of the SGL, we characterized by electrospray ionization tandem mass spectrometry the molecular species of ceramides present in SGL of mouse brain. We report here for the first time the presence in mammalian brain of ... WebSphingoglycolipids (SGLs) are cell membrane constituents especially enriched in the central nervous system. SGLs form specialized structures, mediate cell-cell and cell-substratum interactions, modulate the behavior of cellular proteins and receptors, and participate in signal transduction ( 1 ).

WebJan 19, 2016 · The basic structure of the main epidermal sphingolipids, ceramides, is a sphingoid base with fatty acid connected by an amide bond. Four types of fatty acids (esterified ω-hydroxy [EO], ω-hydroxy [O], α-hydroxy [A] and non-hydroxy [N] fatty acids) with four types of sphingoid bases (sphingosine [S], 6-hydroxysphingosine [H], … Sphingolipids are commonly believed to protect the cell surface against harmful environmental factors by forming a mechanically stable and chemically resistant outer leaflet of the plasma membrane lipid bilayer. Certain complex glycosphingolipids were found to be involved in specific functions, such as cell recognition and signaling. Cell recognition depends mainly on the physical properties of the sphingolipids, whereas signaling involves specific interactions of the glycan str…
