Maltase hydrolyze maltose to form:
**Core Concept**
Maltase is a disaccharidase enzyme that catalyzes the hydrolysis of maltose, a disaccharide composed of two glucose molecules, into two molecules of glucose. This process is essential for the digestion and absorption of carbohydrates in the small intestine.
**Why the Correct Answer is Right**
Maltase acts on the 1,4-glycosidic bond between the two glucose molecules in maltose, specifically at the C-1 carbon of one glucose molecule and the C-4 carbon of the other glucose molecule. This results in the formation of two glucose molecules. The enzyme maltase is a type of sucrase-isomaltase complex, which is located on the brush border membrane of the intestinal epithelial cells.
**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because it does not specify the product of maltase hydrolysis. While glucose is indeed a product, the question asks for the specific form in which it is produced.
**Option B:** Incorrect because it is not a product of maltase hydrolysis. Sucrose is a different disaccharide that is hydrolyzed by a different enzyme, sucrase.
**Option C:** Incorrect because it is not a product of maltase hydrolysis. Fructose is a monosaccharide that is not directly related to the hydrolysis of maltose.
**Clinical Pearl / High-Yield Fact**
Maltase deficiency can lead to an inability to digest maltose, resulting in symptoms such as bloating, gas, and diarrhea. This condition is often seen in individuals with pancreatic insufficiency or small intestine disorders.
**Correct Answer:** D. Glucose.
