Question

The bonds that hold disaccharides and polysaccharides together can be broken by adding a water molecule. This is called​

Answer 1

Disaccharides form when two monosaccharides undergo a dehydration reaction, forming a covalent bond known as a glycosidic bond.

Step-by-step explanation:

Disaccharides (di- = "two") form 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. A covalent bond formed between a carbohydrate molecule and another molecule (in this case, between two monosaccharides) is known as a glycosidic bond or glycosidic linkage. Glycosidic bonds can be of the alpha or beta types.
