Globotriose

Gb3

Globotriose, also known as Gb3, is a specific trisaccharide and a key component of glycolipids called globosides. Its structure is Gal(α1-4)Gal(β1-4)Glc, and it is found on the surface of mammalian cells. This compound serves as an antigen and is a crucial binding site for various pathogens, including the Shiga toxin produced by E. coli, which can lead to severe food poisoning.
