Hyaluronan oligosaccharides are known for their various activities depending on the size as reported by Stern R. et al1). Hyaluronan oligosaccharides are made by an enzyme, hyaluronidase, from hyaluronan polymer extracted from rooster comb or isolated from fermentation products of bacteria. There is a difference between the structure of hyaluronan oligosaccharides made by manmmalian enzymes and by bacterial enzymes.
Oligosaccharides made by hyaluronidase derived from bacteria are called “unsaturated” oligosaccharides because of the double bond between the C-4 and C-5 position of uronic acid at their non-reducing end. On the other hand, oligosaccharides made by hyaluronidase derived from mammalian testis are called “saturated” oligosaccharides because they have no unsaturated bonds. This product is made from hyaluronan polymer purified from fermentation products of streptococcus sp, by digestion with mammalian hyaluronidase derived from ovine testis, and purified by column chromatography2).
