General description

Carbohydrate
Starch is generally composed of two molecule types: amylose and amylopectin. Starch and modified starches are important excipients. They act as fillers/binders.

Application

Starch has been used:

as a component in modified Columbia agar (MCA) to culture and isolate bacterial colonies
in validation studies for determining molar substitution of hydroxyethylstarches (HES) by 1H nuclear magnetic resonance (1H NMR) spectroscopy
as a substrate in anaerobic batch experiments to study the effect of carbohydrates on protein hydrolysis
