GA921000: Fmoc-Ser(β-D-Lac(Ac)7)-OH Pack Size:100 mg 3-Aminopropyl 6’-sialyl LacNAcC44H51NO22 945. 87 An Fmoc protected L serine building block carrying a D lactose (Gal1 4Glc) disaccharide, designed for solid phase peptide synthesis (SPPS) of glycopeptides. The N Fmoc group is removed under standard base conditions (piperidine) during chain elongation, while the free carboxylic acid is available for coupling to the growing resin bound peptide. The sugar hydroxyl groups are protected as seven acetate esters (Ac7), which keep the
