ANNEX In the Annex to Implementing Regulation (EU) 2017/2470, in Table 2 (Specifications), the entry for Lacto- N -neotetraose (microbial source) is replaced by the following: ‘ Lacto- N -neotetraose (microbial source) Definition Chemical name: β-D-Galactopyranosyl-(1→4)-2-acetamido-2-deoxy-β-D-glucopyranosyl-(1→3)-β-D-galactopyranosyl-(1→4)-D-glucopyranose Chemical formula: C 26 H 45 NO 21 CAS No: 13007-32-4 Molecular weight: 707,63 g/mol Description/Source Lacto- N -neotetraose is a white to off-white powder that is produced by a microbiological process using genetically modified strain of Escherichia coli K-12, and/or of Escherichia coli BL21(DE3). An additional optional genetically modified degradation strain of Escherichia coli BL21(DE3) may be used in the production process to degrade intermediate carbohydrate by-products and remaining starting carbohydrate substrates.
