A glycopeptide of the formula S-L-X—P, wherein: S is selected from an optionally protected monosaccharide, an optionally protected polysaccharide, a polyalkylene oxide chain and a group of the formula II, wherein R
1
and R
3
are independently selected from H or Ac, R
4
is Ac, and R
2
is a group of formula IV, wherein R
7
and R
8
are each independently selected from an optionally protected monosaccharide and an optionally protected polysaccharide, A, B, C and D are each independently 1 or 2, and m is 1 to 5; -L- is a moiety of the formula III wherein R
5
and R
6
are independently selected from H and Me and n is 1 to 3; and P is a peptide chain containing at least one amino acid having on its side chain the atom X, wherein X is an oxygen, a sulphur atom or a —CH
2
— moiety.
