3 Terms and definitions
The following terms and definitions apply to this Part of YY/T 0606.
3.1 Hyaluronic acid
It refers to the linear polysaccharide that is composed of disaccharide repeating
structural units generated by connecting D-glucuronic acid and N-acetyl-D-
glucosamine together via β-(1-3) glucosidic bond. Each disaccharide unit is
connected with another unit via β-(1-4) glucosidic bond.
3.2 Sodium hyaluronate
It refers to the sodium salt form of the hyaluronic acid. The molecular weight of
its structural unit is 401. The molecular structural formula is shown in the figure
below.
Note. SEE Appendix D for the additional information about the hyaluronic acid.
5.15 Safety of raw materials
5.15.1 The sodium hyaluronate prepared by using the bio-fermentation
method shall be conducted with the hemolysis test for hemolytic streptococcus.
