GM3
GM3 (monosialodihexosylganglioside) is a type of ganglioside. The letter G refers to ganglioside, and M is for monosialic acid as it has one sialic acid only. The numbering is based on its relative mobility in electrophoresis among other monosialic gangliosides. 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. GM3 serves as a precursor for other, more complex gangliosides. Like other gangliosides, GM3 is synthesized in the Golgi apparatus. It is then transported to the plasma membrane, where it functions in cellular signaling. GM3 also functions as an inhibitor; it inhibits cell growth, the function of growth factor receptors, and generation of cytokines by T cells. Applications in Cancer Treatment The immunologic function of GM3 in inhibiting proliferation has resulted in its usage in the study of cancer biology and cancer trea ...

Ganglioside
A ganglioside is a molecule composed of a glycosphingolipid (ceramide and oligosaccharide) with one or more sialic acids (e.g. ''N''-acetylneuraminic acid, NANA) linked on the sugar chain. NeuNAc, an acetylated derivative of the carbohydrate sialic acid, makes the head groups of gangliosides anionic at pH 7, which distinguishes them from globosides. The name ''ganglioside'' was first applied by the German scientist Ernst Klenk in 1942 to lipids newly isolated from ganglion cells of the brain. 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. Recently, gangliosides have been found to be highly important molecules in immunology. Natural and semisynthetic gangliosides are considered possible therapeutics for neurodegenerative disorders. Location Gangliosides are present and c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Structure Of GM1, GM2, GM3
A structure is an arrangement and organization of interrelated elements in a material object or system, or the object or system so organized. Material structures include man-made objects such as buildings and machines and natural objects such as biological organisms, minerals and chemicals. Abstract structures include data structures in computer science and musical form. Types of structure include a hierarchy (a cascade of one-to-many relationships), a network featuring many-to-many links, or a lattice featuring connections between components that are neighbors in space. Load-bearing Buildings, aircraft, skeletons, anthills, beaver dams, bridges and salt domes are all examples of load-bearing structures. The results of construction are divided into buildings and non-building structures, and make up the infrastructure of a human society. Built structures are broadly divided by their varying design approaches and standards, into categories including building structures, archi ...
