About the structure and biological function of Globosides

Structure. Globosides belong to the sphingolipids. Their structure consists of a ceramide backbone linked to a neutral/non-acidic oligosaccharide “head” group. The number of sugars in the head group is reflected in the name of globoside lipid classes: e.g. Gb4 contains four sugars. The ceramide backbone of globosides contains a hydrocarbon chain termed long-chain base; one fatty acid is linked to the ceramide.

Function. Globosides are present in eukaryotes, such as animals, plants, and fungi. They serve as an important component of the cell membrane, where their sugar head group faces into the extra-cellular space and provides the cell with a protective carbohydrate coating. Further, they interact with hormones and receptors of the signal transduction machinery and thus regulate cellular signaling pathways through many means.

Gb3 and Gb4 are the most investigated globosides and found in mammals. Gb3 accumulation is linked to Fabry’s disease and important to apoptosis, programmed cell death. Gb4 is best known for its role in blood-type determination, where each of the blood group antigens is derived from Gb4. Little is known about the biological functions of globosides in higher plants, algae, and fungi.
