Glucose, fructose and galactose, they are known as monosaccharides and are the only carbohydrates that can be absorbed into the bloodstream through the lining of your intestines. Lactose, sucrose and maltose are disaccharides (they contain two monosaccharides) and are easily converted to their monosaccharide bases in the digestive tract.:):):):)
Nort
Condensation
Galactose and glucose can combine to form the disaccharide lactose, which is the sugar found in milk. This bond is made through a glycosidic linkage between the galactose and glucose molecules.
Lactase catalyzes the hydrolysis of lactose into glucose and galactose. This process can be represented by the following word equation: Lactose + Water → Glucose + Galactose.
Glucose and galactose react to form lactose, a disaccharide composed of one glucose molecule and one galactose molecule, along with a molecule of water. This reaction is a condensation reaction, where a water molecule is removed to form the new compound lactose.
Condensation
Lactose is composed of two monosaccharides: glucose and galactose.
Lactose is the disaccharide produced by combining glucose and galactose.
The principle behind lactose extraction from milk is enzymatic hydrolysis. The enzyme lactase is added to milk, which breaks down lactose into its constituent sugars, glucose and galactose. The chemical reaction can be represented as: Lactose + Water → Glucose + Galactose
Glucose and Galactose make up lactose Glucose and fructose make up sucrose Glucose and glucose make maltose
Glucose, galactose
The chemical equation for the reaction between lactose and lactase is: Lactose + Lactase → Glucose + Galactose
Lactose is a disaccharide sugar made up of galactose and glucose molecules. Galactose is a monosaccharide sugar that is found in milk and dairy products. Lactose needs to be broken down into galactose and glucose in the body in order to be absorbed.
