GA421005: Fmoc-Ser(Gal(Ac)4-α-D)-OH Pack Size:100 mg Fmoc-Thr(β-D-Gal(1-3)[β-D-GlcNAc(1-6)]-α-D-GalNAc)-OH

Fmoc-Thr(β-D-Gal(1-3)[β-D-GlcNAc(1-6)]-α-D-GalNAc)-OH

27 / An α-D-N-acetylgalactosamine (α-D-GalNAc) ligand equipped with an azide-functionalized linker through a short ethyl spacer

This is an Amadori-rearrangement (fructosamine) building block in which the lysine side chain carries a fructose-derived adduct (with the side-chain nitrogen Boc-protected)

66 / An Fmoc-protected L-asparagine building block carrying a β-D-GlcNAc residue

GA421005: Fmoc-Ser(Gal(Ac)4-α-D)-OH Pack Size:100 mg Fmoc-Thr(β-D-Gal(1-3)[β-D-GlcNAc(1-6)]-α-D-GalNAc)-OHC32H35NO14 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
