GA821005: Fmoc-Ser((Ac)3-Rha-β-L)-OH Pack Size:250 mg 27 / MUC1 (UniProt IDC24H27NO9 473. 47 An Fmoc protected L serine building block carrying a L rhamnose 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 three acetate esters (Ac3), which keep the glycan inert during
