globosydy
Globosydy, known in English as globosides, are a class of neutral glycosphingolipids found in cell membranes. They consist of a ceramide backbone linked to an oligosaccharide chain that typically contains multiple sugar residues and lacks sialic acid. They are distinct from gangliosides, which carry sialic acid, and cerebrosides, which have a single sugar.
They are widely distributed in animal tissues, enriched in certain membranes; they participate in membrane organization,
Biosynthesis occurs in the Golgi apparatus via glycosyltransferases that extend a ceramide with sugar units; catabolism
A well-known example is Gb3, which serves as the receptor for Shiga toxins produced by Shigella dysenteriae
