Chemical Synthesis and Structural Determination of the Inositol Glycan Head of Plant Sphingolipid GIPC in Brassicaceae

Chemistry – A European Journal, EarlyView.
The first experimental identification of the IG head structure of naturally occurring plant GIPCs in Brassicaceae was achieved through the chemical synthesis of three hexose‐type IGs containing d‐glucose, d‐galactose, or d‐mannose as the second monosaccharide linked to d‐glucuronic acid‐α(1→2)‐myo‐inositol.
