General description

The Oligo-HA products are small-molecular weight hyaluronic acid prepared with streptococcal or recombinant bacterial HA via testicular HAase digestion and purified by gel filtration. The hyaluronan disaccharide subunit is glucuronic acid-β-D-(1→3)-N-acetyl-D-glucosamine-β-D-(1→4) (GlcAβ3GlcNAcβ4), and each Oligo-HA is an defined oligomer of the subunit.

Application

Oligo-HA4 has been used in a study to assess microbial production and applications of chiral hydroxyalkanoates. It has also been used in a study to investigate in situ preparation and continuous fiber spinning of poly(p-phenylene benzobisoxazole) composites.

Other Notes

Oligo-HA4 is a monodisperse tetrasaccharide comprised of two hyaluronan disaccharide subunits (Nonreducing-GlcAβ3GlcNAcβ4GlcAβ3GlcNAcβ4-reducing end).
To gain a comprehensive understanding of our extensive range of Oligosaccharides for your research, we encourage you to visit our Carbohydrates Category page.

Analysis Note

May contain trace amounts of other oligomers. Sold on the basis of carbohydrate as determined by carbazole assay.

Polyhydroxyalkanoates (PHA) are a family of polyesters consisting of over 150 chiral hydroxyalkanoic acids (HA). This paper reviews the physiological functions of (R)-3-hydroxybutyric acid (3HB) and (R)-4-hydroxybutyric acid and summarizes the technologies developed to produce various HA [3HB, (R)-3-hydroxyoctanoic acid
