WitrynaSphingomyelin or ceramide 1-phosphocholine is a sphingophospholipid that consists of a ceramide unit with a phosphorylcholine moiety attached to position 1 of the sphingoid base component. It is thus the sphingolipid analogue of phosphatidylcholine, and like that lipid it is zwitterionic, although the similarities between the two do not extend … WitrynaThe sphingolipids are one of the major lipid families in eukaryotes, incorporating a diverse array of structural variants that exert a powerful influence over cell fate and …
WitrynaStructure. The essential feature of a glycolipid is the presence of a monosaccharide or oligosaccharide bound to a lipid moiety.The most common lipids in cellular membranes are glycerolipids and sphingolipids, which have glycerol or a sphingosine backbones, respectively.
