Step-by-step explanation:
Disaccharides are carbohydrates composed of two monosaccharide units linked together through a dehydration synthesis (condensation) reaction. There are several types of disaccharides, but three of the most common ones are:
Sucrose: Sucrose is a disaccharide composed of two monosaccharides: glucose and fructose. It is commonly found in sugar cane, sugar beets, and various fruits. When glucose and fructose molecules combine through a glycosidic bond, they form sucrose, which is commonly known as table sugar.
Chemical formula: C12H22O11
Monomers: Glucose + Fructose
Lactose: Lactose is a disaccharide found in milk and dairy products. It consists of two monosaccharides: glucose and galactose. Lactose is broken down into these monomers by the enzyme lactase in the digestive system.
Chemical formula: C12H22O11
Monomers: Glucose + Galactose
Maltose: Maltose is a disaccharide made up of two glucose molecules linked together. It is often formed during the digestion of starch, making it an intermediate product in the breakdown of complex carbohydrates.
Chemical formula: C12H22O11
Monomers: Glucose + Glucose
