Polygalacturonic Acid
 
  • Methylated Polygalacturonic Acid :
  • Appearance : Light Yellow To Beige Powder
  • Assay : >= 85-94 % (titration)
  • Solubility : Aqueous NaOH: soluble1%, clear to hazy.
 

Polygalacturonic acid, which consists of chains of 300 to 1000 galacturonic acid units joined with 1alph->4 linkages. The structure shown here has three methyl ester forms) for every two carboxyl groups (-COOH), hence it is has a 60% degree of esterification
