GA421005: Fmoc-Ser(Gal(Ac)4-α-D)-OH Pack Size:250 mg β-D-Glc-Bu-CO2HC32H35NO14 657. 62 An Fmoc protected L serine building block carrying an D galactose residue, 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 four acetate esters (Ac4), which keep the glycan inert
