Pentastarch definition
Pentastarch means a hydroxyethyl starch, an artificial colloid derived from a waxy starch composed almost entirely of amylopectin, with hydroxyethyl ether groups introduced into the glucose units of the starch. The resultant material is hydrolyzed to yield a product suitable for the intended use. Molar substitution of hydroxyethyl ether groups is between approximately
Pentastarch means a hydroxyethyl starch, an artificial colloid derived from a waxy starch composed almost entirely of amylopectin, with hydroxyethyl ether groups introduced into the glucose units of the starch. The resultant material is hydrolyzed to yield a product suitable for the intended use. Molar substitution of hydroxyethyl ether groups is between approximately 0.4 to 0.6, meaning that there are approximately 4 to 6 hydroxyethyl groups for every 10 glucose units. The average molecular weight of the resultant material between 150,000 to 350,000, and excludes High Molecular Weight Hetastarch.
