Starch, soluble
Starch, soluble (CAS: 9005-84-9) is a readily soluble form of starch, a polysaccharide composed of D-glucose units. It is characterized by its ability to form colloidal solutions in water, making it distinct from insoluble starch. This soluble starch serves as a critical reagent in various analytical and biochemical applications, particularly where a well-defined carbohydrate source is required. Its properties make it valuable in laboratory settings for research and quality control.
