Alkali-labile gangliosides

open access: yesGlycoconjugate Journal, 2023
AbstractThe structure and properties of a group of gangliosides modified by mild alkaline treatment are discussed. We will present the occurrence and the structure of gangliosides carrying the N-acetyneuraminic acid O-acetylated in position 9, the Neu5,9Ac2, and of gangliosides carrying a sialic acid that forms a lactone ring. Starting from biochemical
