Gangliosides are acidic glycosphingolipids that contribute a substantial presence to the outer leaflet of the cell plasma membrane. This is especially apparent in neuronal cells of the central nervous system where they have vital roles as neurotransmitters and cellular regulators.1 They participate in cellular proliferation, differentiation, adhesion, signal transduction, cell-to-cell interactions, tumorigenesis, and metastasis.2 Gangliosides have been implicated in numerous types of cancer where they are often over-expressed on the membrane surface.3 A deficiency in the enzymes responsible for metabolizing gangliosides allows them to accumulate to toxic levels in several lysosomal storage diseases including GM1 gangliosidosis, GM2 gangliosidosis, Tay-Sachs disease, and Sandhoff disease. Matreya now offers a number of high purity deuterated gangliosides which are ideal for mass spectrometry studies.4

Fatty Acid Composition of Matreya's Natural Lipids

Natural sphingolipids contain a heterogeneous mixture of fatty acids attached to the sphingosine moiety. The fatty acid composition is dependent on several factors including species, location within the organism, age, and environmental conditions. Normal variations in the fatty acids include chain-length, hydroxylation, and unsaturation. The percentages listed are only approximates as the actual amount will vary between lots.
