Invert sugar, is
**Core Concept**
Invert sugar is a type of disaccharide formed from sucrose, which is broken down into glucose and fructose through a process called hydrolysis. This reaction is catalyzed by the enzyme sucrase, also known as invertase. The resulting mixture of glucose and fructose is known as invert sugar.
**Why the Correct Answer is Right**
Invert sugar is formed when sucrose is hydrolyzed into its constituent monosaccharides, glucose and fructose. This process occurs through an enzymatic reaction catalyzed by sucrase, which breaks the glycosidic bond between the two sugars. As a result, the mixture of glucose and fructose is known as invert sugar. This process is commonly used in the food industry to produce invert sugar, which is used as a sweetener and preservative.
**Why Each Wrong Option is Incorrect**
**Option A:** Sucrose is not broken down into glucose and fructose through an enzymatic reaction.
**Option B:** Fructose is not a product of the hydrolysis of sucrose.
**Option C:** Glucose is not a product of the hydrolysis of sucrose.
**Clinical Pearl / High-Yield Fact**
It's worth noting that invert sugar is commonly used in the food industry as a sweetener and preservative, and is also used in the preparation of certain medications, such as cough syrups.
**Correct Answer: D.**
