  • Patent number: 10696995
    Abstract: The present invention relates to a method for producing a glycosylated synthon or a monomer. Said method includes at least one step of placing at least one glycan-saccharase in the presence of at least one hydroxylated synthon and at least one saccharose. The invention also relates to a method for producing a glyco(co)polymer, including polymerizing at least two monomers separately obtained from the enzymatic glycosylation method according to the invention, and to a method for producing a glyco(co)polymer, preferably a block glyco(co)polymer, including coupling at least two monomers separately obtained from the enzymatic glycosylation method according to the invention.
