Glycosphingolipids (GSLs) are a complex and diverse class of lipid molecules that are widely present in the cell membranes of eukaryotic organisms. GSLs are composed of three parts: hydrophobic sphingosine backbone, glycosyl portion, and functional group attached to the glycosyl portion. GSLs are not only structural components, but also participate in biological functions such as cell recognition, signal transduction, and immune response. CD BioGlyco is committed to providing clients with high-quality GSL products to help them achieve greater breakthroughs in scientific research.

These products undergo strict quality control to ensure their purity and functionality and are suitable for research in the fields of immunology, intestinal microbiology, cancer, neuroscience, etc.

Lacto-series Glycolipids

Lacto-series GSLs are a class of structurally diverse and functionally rich molecules, characterized by multiple extended forms and carrying complex glycan epitopes and antigenic properties. The addition of N-acetylglucosamine (GlcNAc) to lactosylceramide (LacCer) forms lactotriosylceramide (Lc3), a key precursor molecule for all neo-lacto series GSLs. Further expansion of Lc3 is achieved through β1-3 or β1-4 galactose residues. This expansion method not only increases the structural complexity of the molecule but also enhances its specific recognition and signal transduction functions in the body. The lacto-series GSL products we provide to clients include but are not limited to:

Globo-series Glycolipids

The production of Globo-series GSLs begins with the attachment of α1-4 galactose to LacCer to generate a trisaccharide ceramide molecule Gb3. The more complex tetrasaccharide ceramide Gb4 is formed by adding β1-3 bonded N-acetylgalactosamine (GalNAc) to Gb3. This increase in structure gives these molecules greater diversity and specific biological functions. The Globo-series GSLs we provide to our clients include but are not limited to:

Ganglio-series Glycolipids

Ganglio-series GSLs are a group of highly important glycolipids in the nervous system. Ganglio-series GSLs are subdivided into three subseries: a, b, and c, depending on the different sialic acid structures attached. α2-3 sialic acid is added to the galactose residues of LacCer to form monosialoglycolipids, namely the ganglioside a series. The b series is based on the existing ganglioside a series, and α2-8 sialic acid is further added to α2-3 sialic acid. The uniqueness of the c series GSL lies in its derived multi-layer sialic acid modification, with Neu5Acα(2-8)Neu5Acα(2-8)Neu5Acα2-3 substitutions. The ganglio-series GSLs we provide include but are not limited to:
