C18 Ganglioside GD3-d3 (ammonium salt) (Synonyms: Disialosyllactosylceramide-d3, N-omega-CD3-Octadecanoyl Disialoganglioside GD3-d3)

C18 Ganglioside G_D3-d₃ is intended for use as an internal standard in the quantification of ganglioside G_D3 by GC- or LC-MS. Ganglioside G_D3 is synthesized by the addition of two sialic acid residues to lactosylceramide and can serve as a precursor to the formation of more complex gangliosides by the action of glycosyl- and sialyltransferases. With roles in cell proliferation and differentiation, its expression increases during development and in pathological conditions such as cancer.¹ Furthermore, the intracellular accumulation of ganglioside G_D3 can contribute to mitochondrial damage, a crucial event during apoptosis.² Ganglioside G_D3 has become a target for therapeutic approaches to prevent malignant properties of tumor cells like melanoma.^1,3 [Matreya, LLC.
