4-O-β-Galactopyranosyl-D-mannopyranoside（Cat No.:R000894）, also known as GM4, is a glycosphingolipid found in the membranes of cells, particularly in the nervous system. It consists of a β-galactopyranosyl residue linked to the 4-hydroxyl group of a D-mannopyranosyl residue. GM4 plays a role in cell recognition and signaling processes. It is involved in cell-cell interactions and is a precursor to more complex glycosphingolipids. GM4 has been studied for its potential involvement in neurological disorders and cancer.
