What product does maltase produce?
During digestion, starch is partially transformed into maltose by the pancreatic or salivary enzymes called amylases; maltase secreted by the intestine then converts maltose into glucose. The glucose so produced is either utilized by the body or stored in the liver as glycogen (animal starch).
What are the substrate and products of maltase?
For amylase the substrate is amylose and amylopectin which are the components of the starch mixture, and for maltase it is the maltose sugar which is the substrate….What substrate does maltase act on?
| Enzyme | Substrate | End-products |
|---|---|---|
| Pancreatic amylase | Starch | Maltose |
| Maltase | Maltose | Glucose |
What are the products when maltase breaks down maltose?
Maltase breaks down maltose into glucose. Other disaccharides, such as sucrose and lactose are broken down by sucrase and lactase, respectively. Sucrase breaks down sucrose (or “table sugar”) into glucose and fructose, and lactase breaks down lactose (or “milk sugar”) into glucose and galactose.
What is the product of glucose and maltose?
Three common disaccharides: sucrose — common table sugar = glucose + fructose. lactose — major sugar in milk = glucose + galactose. maltose — product of starch digestion = glucose + glucose.
Why is maltase useful?
The enzyme maltase helps to relieve the burden of digestion on the pancreas and the small intestine. Without this important enzyme, the small intestine has a much harder time breaking down sugars and starches. In this way, maltase helps the entire digestive system function smoothly.
What is the pH of maltase?
Some properties of the partially purified maltase were determined: optimum pH, 6.5; optimum temperature, 48 to 50°C; pH stability range, 5.0 to 7.0; temperature stability range, 0 to 50°C; isoelectric point, pH 5.2; and molecular weight, 52,000.
Why is maltase important?
Maltase is one of the most important enzymes in our digestive process, as it is a key enzyme in the mouth and the saliva. Without this important enzyme, the small intestine has a much harder time breaking down sugars and starches. In this way, maltase helps the entire digestive system function smoothly.
Is glucose a six carbon sugar?
Glucose is a hexose, with six carbon atoms (Fig. 5.41), and an aldehyde-aldose monosaccharide.
What is the final product of maltose digestion?
glucose molecules
Maltose is digested to two glucose molecules in the intestine by the action of the enzyme maltase.
What is the product of the enzyme maltase?
The digestion of maltose involves the action of the enzyme maltase. The product is glucose. What is the product for salivary amylase? Maltose, then later in the digestive system, Maltase digests Maltose to Glucose
Which is the breakdown of starch into maltose?
Amylase catalyses the breakdown of starch into maltose in the mouth and small intestine Maltase catalyses the breakdown of maltose into glucose in the small intestine 1 2
Which is the only vertebrate to not exhibit maltase activity?
Vampire bats are the only vertebrates known to not exhibit intestinal maltase activity. Maltase is part of a group of intestinal enzymes called FamilyGH13 ( Glycoside hydrolase family 13) that are responsible for breaking apart the α-glucosidase linkages of complex carbohydrates into simple to use glucose molecules.
What is the difference between maltase and alpha glucosidase?
Maltase. In most cases, it is equivalent to alpha-glucosidase, but the term “maltase” emphasizes the disaccharide nature of the substrate from which glucose is cleaved, and “alpha-glucosidase” emphasizes the bond, whether the substrate is a disaccharide or polysaccharide.
