Question

What are disaccharides?

Answer 1

Hint: Carbohydrates are macronutrients and one of the three basic sources of energy for our bodies. Carbohydrates, which comprise sugars, fibres, and starches, are necessary nutrients. They can be found in cereals, vegetables, fruits, and dairy products such as milk and cheese. Carbohydrates are divided into two categories: simple and complicated, based on their chemical structure and degree of polymerization.

Complete answer:
Disaccharides are carbohydrates that, when hydrolysed with acids or enzymes, provide two monosaccharide molecules that can be the same or different. After the water molecule is lost, the oxide linkage is produced, and the two monosaccharides are generated by that bond. A glycosidic linkage occurs when two monosaccharide units are linked together by an oxygen atom. Disaccharides include sucrose, maltose, and lactose, which are all readily available.
Examples of Disaccharides
Sucrose is a non-reducing sugar since the glycosidic bond formation involves both the reducing groups of glucose and fructose. Sucrose table sugar and the most common disaccharide consumed by humans.
Maltose is a disaccharide that consists of two -D-glucose units joined by the first carbon of the glucose and also attached to the fourth carbon of another glucose unit. Maltose is a sweetener commonly found in chocolates and other confections.
Lactose is also known as milk sugar because it is a disaccharide found in milk. Beta-D-galactose and -D-glucose are the two sugars that make it up. The bond is formed between galactose's first carbon and glucose's fourth carbon.

Note:
Disaccharides are carbohydrates that when hydrolysed give two simple monosaccharides. The monosaccharides that result may be the same or different. The condensation of the hydroxyl group of one monosaccharide's anomeric carbon with the hydroxyl group of another carbohydrate with the removal of water results in disaccharides. Disaccharides are a type of carbohydrate that can be found in a variety of foods and are frequently used as sweeteners. Breast milk contains lactose, which gives nutrients to new-borns. In some algae and fungi, trehalose is employed for transport.
