GA931010: Fmoc-Thr((Ac)7-Mal-β-D)-OH Pack Size:100 mg 38 / A peracetylated β-D-N-acetylgalactosamineC45H53NO22 959. 9 An Fmoc protected L threonine building block carrying a maltose (Glc1 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
