Final answer:
A glycosidic bond connects two monosaccharides to form a disaccharide via a dehydration synthesis process, resulting in crucial compounds like sucrose, lactose, and maltose.
Step-by-step explanation:
The type of bond connecting two monosaccharides to form a disaccharide is called a glycosidic bond. This covalent bond is formed through a process known as dehydration synthesis, where a water molecule is released as the hydroxyl group of one monosaccharide combines with the hydrogen of another. The resulting structure, a disaccharide, is important in various biological functions and is a major source of energy for living cells. Disaccharides like sucrose, lactose, and maltose need to be broken down into their monosaccharide units before our bodies can use them.
A disaccharide is formed when two monosaccharides undergo a dehydration reaction, also known as a condensation reaction or dehydration synthesis. During this process, the hydroxyl group of one monosaccharide combines with the hydrogen of another monosaccharide, releasing a molecule of water and forming a covalent bond. This covalent bond is called a glycosidic bond or glycosidic linkage.
