- British English: /ˌæmɪˈdjuːlɪn/
- U.S. English: /ˌæmɪˈduːlɪn/
- Rhyming Words: mandolin, insulin, disciplin
- First Known Use: 1848
Etymology
The term amidulin is derived from the German word Amidulin, itself rooted in amido- (related to amide groups) and ulin, a suffix commonly used in chemistry to denote a substance. The word reflects its role as a chemical derivative of starch.
Meaning & Use
Definition
- A Soluble Form of Starch:
Amidulin is a form of starch created by partial hydrolysis, typically using acid. It serves as an intermediate compound between true starch and other derivatives like dextrin or inulin.- Example: “Amidulin plays a role in various chemical and industrial processes due to its solubility and reactive properties.”
Chemical Characteristics
- Formation: Produced when starch undergoes controlled hydrolysis.
- Properties: Soluble in water and reacts with iodine, often coloring blue.
Quotations in Context
- 1848:
“Notice respecting Amiduline… I have applied the above name to a modification of starch which forms the transition between true starch and inuline or dextrine.”
— Translation of F. Schulze, Chemical Gazette - 1917:
“Hale found that ordinary starch contains as impurities, erythrodextrin, coloring red with iodine, and amidulin, coloring blue.”
— Journal of Industrial & Engineering Chemistry - 2018:
“Sodium sulfide (4 g), amidulin (3.5 g), sucrose (2 g), sodium tetraborate (0.5 g), and glycerin (2.5 g) were carefully weighed and dissolved in 50 mL of water.”

Pronunciation
- Phonetic:
- British: /ˌæmɪˈdjuːlɪn/
- American: /ˌæmɪˈduːlɪn/
- Rhyming Words: mandolin, insulin, disciplin
The stress falls on the second syllable (-du- or -dju-), and the word ends with a soft -lin.
Examples in Everyday Use

- Industrial Chemistry:
- “Amidulin’s solubility makes it a key component in adhesives and coatings.”
- Biochemical Studies:
- “The study analyzed the effects of iodine on amidulin and other starch derivatives.”
Synonyms
- Soluble starch derivative
- Hydrolyzed starch
- Starch intermediate
Applications and Importance
- Chemical Research:
Amidulin is studied in the context of starch derivatives and their transformations, particularly in processes involving hydrolysis. - Industrial Uses:
Its properties make it suitable for use in adhesives, coatings, and as a precursor in manufacturing other compounds. - Pharmaceuticals:
Amidulin can appear in formulations where modified starch derivatives are required for binding or reactivity.
Conclusion
Amidulin is a specialized term in chemistry, representing a soluble starch derivative formed by partial hydrolysis. With its roots in 19th-century scientific research, it continues to be relevant in industrial applications and biochemical studies. Its versatility and reactivity highlight its significance in advancing our understanding and utilization of starch-based compounds.
