Acetylated oxidized starch

Description:Acetylated oxidized starch is a food and beverage ingredient used as a thickener.It is a chemically modified root or grain starch. It is produced by oxidation of a slurry of starch granules in alkaline hypochlorite at low temperature (21–38 °C). The alkaline medium is neutralized with sodium bisulfite, and the resulting organic salts are removed by washing with water. The oxidized starch is then esterified with acetic anhydride under mildly alkaline conditions.

Epiandrosterone


Product name:Epiandrosterone
CAS: 481-29-8
Molecular Formula:     C19H30O2
Formula Weight:290.44
Description:
       Epiandrosterone is a steroid hormone with weak androgenic activity. It is a natural metabolite of dehydroepiandrosterone via the 5-alpha reductase enzyme. 
      Epiandrosterone has been shown to naturally occur in most mammals including pigs.
      Epiandrosterone is naturally produced by the enzyme 5-alpha reductase from the adrenal hormone dehydroepiandrosterone (DHEA).Epiandrosterone can also be converted from the natural steroids androstanediol via 17β-hydroxysteroid dehydrogenase or from androstanedione via 3β-hydroxysteroid dehydrogenase.
