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 ...
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 ]
While in gangliosides sialic acids are found, sulfatides have a sulfate group. The structural similarity of most glycolipids is the so-called lactosylceramide, that is, a lactose disaccharide that is glycosidically bound to a ceramide.
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 ...
Plasmalogens are found in numerous human tissues, with particular enrichment in the nervous, immune, and cardiovascular systems. [1] [2] [3] In human heart tissue, nearly 30–40% of choline glycerophospholipids are plasmalogens. Even more striking is the fact that 32% of the glycerophospholipids in the adult human heart and 20% in brain and up ...
Globoside 4 (Gb4) has been known as the receptor for parvovirus B19, due to observations that B19V binds to the thin-layered chromatogram of the structure.However, the binding on its surface does not match well with the virus, which raised debates on whether or not GB4 is the cause for productive infection.

Haematopoietic stem cell transplantation (HSCT) is the transplantation of multipotent haematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood. [ 10 ] [ 11 ] [ 12 ] It may be autologous (the patient's own stem cells are used), allogeneic (the stem cells come from a donor) or syngeneic (from an ...
Sphingolipidoses are a class of lipid storage disorders or degenerative storage disorders caused by deficiency of an enzyme that is required for the catabolism of lipids that contain ceramide, [1] also relating to sphingolipid metabolism.
