A complex molecule that contains both lipids (fats) and carbohydrates (sugars) and is found in the plasma (outer) membrane of many kinds of cells. Several different types of gangliosides have been identified.
Any glycolipid containing one or more N-acetylneuraminic acid (sialic acid) residues in its structure. Gangliosides are found in the plasma membrane of eukaryotic cells and are especially abundant in neurons; they confer a net negative charge on most animal cells.
Any glycolipid having one or more sialic acid residues in its structure. Found in the plasma membrane of eucaryotic cells and especially abundant in nerve cells.
