What function does maltose have?
Maltose is used as a source of energy, not only in plants but also in animals. Mature plants use Maltose in the early energy harvesting process, and seeds also use Maltose for the energy needed to germinate and grow. In animals, Maltose in the diet serves as a source of glucose.

What is the function of lactose sugar?
Lactose is widely used in food and pharmaceutical industries. Applications range from an energy source for lactic acid bacteria during dairy-product fermentation, in which its breakdown leads to the formation of specific flavor components, to its use as an excipient in oral, solid-dose pharmaceutical formulations [2].
What is the function of Disaccharidase?
Disaccharidases are a group of enzymes of the small intestinal brush border, that are essential for degradation of disaccharides (sucrose, lactose, maltose, isomaltose, trehalose) into monosaccharides, which are then absorbed from the gastrointestinal tract.
What is the function of sucrase maltase and lactase?
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 maltose in digestion?
Maltose is a disaccharide containing two glucose molecules. Maltose is digested to two glucose molecules in the intestine by the action of the enzyme maltase.
What is glucose function?
A primary role for the glucose molecule is to act as a source of energy; a fuel. Plants and animals use glucose as a soluble, easily distributed form of chemical energy which can be ‘burnt’ in the cytoplasm and mitochondria to release carbon dioxide, water and energy.
What do you mean by maltose?
Medical Definition of maltose : a crystalline dextrorotatory fermentable disaccharide sugar C12H22O11 formed especially from starch by amylase (as in saliva and malt), as an intermediate reducing product in metabolism, and in brewing and distilling and used chiefly in foods and in biological culture media.
Is maltose a glucose?
Maltose consists of two molecules of glucose that are linked by an α-(1,4′) glycosidic bond. Maltose results from the enzymatic hydrolysis of amylose, a homopolysaccharide (Section 26.9), by the enzyme amylase. Maltose is converted to two molecules of glucose by the enzyme maltase, which hydrolyzes the glycosidic bond.
What is Palatinase?
Palatinase (also called sucrase-isomaltase) is a brush-border disaccharidase enzyme that hydrolyzes palatinose. Congenital sucrase-isomaltase deficiency (CSID) is a genetic condition affecting the digestion of some sugars. People with this condition cannot break down the sugars sucrose and maltose.
What happens in Disaccharidase deficiency?
Disaccharidase deficiency can cause malabsorption of carbohydrates. The unabsorbed sugars can serve as an osmotic load in the small bowel, drawing fluid into the lumen and leading to intestinal distension and rapid propulsion into the colon.
What secretes maltase lactase and sucrase?
Pancreatic juices also contain amylase, which continues the breakdown of starch and glycogen into maltose, a disaccharide. The disaccharides are broken down into monosaccharides by enzymes called maltases, sucrases, and lactases, which are also present in the brush border of the small intestinal wall.
Why is maltase important?
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.
Where is maltose digested?
Small intestine
Where enzymes are produced
| Enzyme | Substrate | Where produced |
|---|---|---|
| Protease | Protein | Stomach, pancreas |
| Lipase | Lipids (fats and oils) | Pancreas |
| Pancreatic amylase | Starch | Pancreas |
| Maltase | Maltose | Small intestine |
What is maltose in biology?
Maltose (/ˈmɔːltoʊs/ or /ˈmɔːltoʊz/), also known as maltobiose or malt sugar, is a disaccharide formed from two units of glucose joined with an α(1→4) bond. In the isomer isomaltose, the two glucose molecules are joined with an α(1→6) bond.
What is maltose made of?
Maltose is, technically, a double sugar, since it is composed of two molecules of the simple sugar glucose bonded together. The digestive enzyme maltase catalyzes a reaction in which a molecule of water is inserted at the point at which the two glucose…
What contains maltose?
Several foods naturally contain maltose (2). You can find it in wheat, cornmeal, barley and several ancient grains. Many breakfast cereals also use malted grains to add natural sweetness. Fruits are another common source of maltose in the diet, especially peaches and pears.
How is maltose digested?
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 is the action of maltase?
This enzyme catalyzes the hydrolysis of disaccharide maltose into two simple sugars of glucose. Maltase is found in plants, bacteria, yeast, humans, and other vertebrates. It is thought to be synthesized by cells of the mucous membrane lining the intestinal wall.
