Description

General description

Hydroxyethyl starch is a non-ionic starch derivative. It is categorized based on its in vitro molecular weight. A 6% concentration is commonly preferred with 130 kD and 0.38 to 0.45 of molecular weight and molar substitution ratios respectively. Degree of substitution; Average of 1 -OH group per 10 glucose units converted to -OCH2CH2OH.

Application

Hydroxyethyl starch has been used to study its shear response. It has also been used as a macromolecular compound in the medium for sperm isolation, culture and cryopreservation.

Packaging

1 kg in poly bottle

250 g in poly bottle

Biochem/physiol Actions

Hydroxyethyl starch (HES) is a colloid used for medicinal practices that involve fluid replacement. It acts as a plasma substitute. Acute kidney failure risk is increased by the use of HES in patients with severe sepsis.

Linkage

The similar Hetastarch (q.v.) is substituted to the extent of 7-8 groups per 10 glucose units.

Preparation Note

Prepared from corn starch
