More than 60 gangliosides are known, which differ from each other mainly in the position and number of NANA residues. It is a component of the cell plasma membrane that modulates cell signal transduction events, and appears to concentrate in lipid rafts [2] [3]. Recently, gangliosides have been found to be highly important molecules in ...
[5] [6] Gangliosides can be found on neuronal cells and are membrane proteins that aid in cell-cell recognition and communication. PglC belongs to a superfamily of enzymes known as monotopic phosphoglycsoyl transferases (monoPGT).
The numbering is based on its relative mobility in electrophoresis among other monosialic gangliosides. [1] Its structure can be condensed to NANA - Gal - Glc - ceramide . GM3 is the most common membrane-bound glycosphingolipid in tissues, composed of three monosaccharide groups attached to a ceramide backbone. [ 2 ]

The secreted toxin attaches to the surface of the host mucosa cell by binding to GM1 gangliosides. GM1 consists of a sialic acid-containing oligosaccharide covalently attached to a ceramide lipid. The A1 subunit of this toxin will gain entry to intestinal epithelial cells with the assistance of the B subunit via the GM1 ganglioside receptor.
Sphingomyelin (SPH, ˌsfɪŋɡoˈmaɪəlɪn) is a type of sphingolipid found in animal cell membranes, especially in the membranous myelin sheath that surrounds some nerve cell axons. It usually consists of phosphocholine and ceramide, or a phosphoethanolamine head group; therefore, sphingomyelins can also be classified as sphingophospholipids.
This enzyme catalyzes the biodegradation of fatty acid derivatives known as gangliosides. [1] The diseases are better known by their individual names: Tay–Sachs disease, AB variant, and Sandhoff disease. Beta-hexosaminidase is a vital hydrolytic enzyme, found in the lysosomes, that breaks down lipids. When beta-hexosaminidase is no longer ...
