diastase
Definition
- Noun:
- An enzyme complex: "diastase" refers to a group of enzymes that catalyze the breakdown of starch into sugars, such as maltose. It is commonly found in germinating seeds, malt, and some microorganisms.
- A historical term in biochemistry: In earlier usage, "diastase" was a general term for any enzyme that breaks down complex carbohydrates, but it now specifically denotes amylolytic enzymes.
Usage Examples
- Noun:
- The diastase in malt helps convert starch into fermentable sugars during beer brewing. (The enzyme complex breaks down starch into simpler sugars.)
- Diastase is used in the food industry to produce sweeteners from starch. (The enzyme is applied commercially for starch hydrolysis.)
Advanced Usage
"diastase activity": the measure of the enzymatic power of diastase to break down starch.
- The diastase activity of the barley sample was high, indicating good malting quality. (The enzyme's effectiveness in converting starch was strong.)
"diastase number": a value representing the amount of diastase present in a substance, often used in quality testing of honey or malt.
- Honey with a low diastase number may indicate overheating or adulteration. (The enzyme content is a quality indicator.)
Variants and Related Words
Diastatic (adj): relating to or involving diastase.
- The diastatic power of the yeast is crucial for bread rising. (The enzyme's ability to break down starch affects fermentation.)
Diastasis (n): a medical term for the separation of normally joined parts, such as abdominal muscles; not directly related to the enzyme.
Synonyms
Amylase: a more modern term for the specific enzyme group that breaks down starch.
- Amylase is a synonym for diastase in many contexts. (Both refer to starch-digesting enzymes.)
Starch-digesting enzyme: a descriptive phrase for the function of diastase.
