Glycolipids are lipids with a carbohydrate attached by a glycosidic (covalent) bond. Their role is to maintain the stability of the cell membrane and to facilitate cellular recognition, which is crucial to the immune response and in the connections that allow cells to connect to one another to form tissues.
L 681217 is a glycolipid-type antibiotic related to the efrotomycin class. L-681217 inhibits bacterial protein synthesis at the elongation stage. L 681217 shows broad-spectrum antibiotic activity against Gram-positive and Gram-negative bacteria.
Ganglioside GM1 asialo is a component of cellular lipid rafts and can be formed by the cleavage of the sialic acid residue from ganglioside GM1 by neuraminidase. Ganglioside GM1 asialo is a glycolipid receptor for P. aeruginosa flagellin and stimulates defensive responses in host cells, including extracellular ATP release, calcium mobilization, and ERK1/2 phosphorylation when stimulated by flagellin and an anti-ganglioside GM1 asialo antibody. The percentage of ganglioside GM1 asialo-positive natural killer (NK) and CD8+ T cells in lung is increased in a mouse model of respiratory syncytial virus (RSV) infection compared with healthy animals. Depletion of ganglioside GM1 asialo-positive NK and T cells reduces IFN-γ levels in the lung, reduces weight loss, and increases lung viral load in RSV-infected mice. Ganglioside GM1 asialo mixture contains ganglioside GM1 asialo molecular species with C18:1 and C20:1 sphingoid backbones.
Tetracosanoyl-sulfatide is an endogenous sulfated glycolipid, which are also known as sulfatides . Tetracosanoyl-sulfatide is the major sulfatide in mature myelin in the central and peripheral nervous systems. Levels of Tetracosanoyl-sulfatide are elevated in plasma derived from patients with metachromatic leukodystrophy, a disorder characterized by arylsulfatase A deficiency, leading to sulfatide accumulation. Unlike C24:1 3'-sulfo galactosylceramide, it does not induce an immune response in mouse splenocytes in vitro.
10-Methyl palmitic acid methyl ester is a methylated derivative of fatty acid methyl ester, identified in glycolipid analogs with cyclitol from P. crassa. [Matreya, LLC. Catalog No. 1792]
