Question

What type of reaction causes the formation of sugar molecules larger than monosaccharides

Answer 1

Disaccharides are formed when two monosaccharides undergo a dehydration reaction, joining them together through 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. This covalent bond formed between two monosaccharides is known as a glycosidic bond or glycosidic linkage.

Answer 2

Carbohydrates

Carbohydrates (also called saccharides) are molecular compounds made from just three elements: carbon, hydrogen and oxygen. Monosaccharides (e.g. glucose) and disaccharides (e.g. sucrose) are relatively small molecules. They are often called sugars. Other carbohydrate molecules are very large (polysaccharides such as starch and cellulose).

Carbohydrates are:

1. A source of energy for the body e.g. glucose and a store of energy, e.g. starch in plantsbuilding blocks for polysaccharides (giant carbohydrates), e.g. cellulose in plants and glycogen in the human body components of other molecules eg DNA, RNA, glycolipids, glycoproteins, ATPMonosaccharides2. Monosaccharides are the simplest carbohydrates and are often called single sugars. They are the building blocks from which all bigger carbohydrates are made.3. Monosaccharides have the general molecular formula (CH2O)n, where n can be 3, 5 or 6. They can be classified according to the number of carbon atoms in a molecule:
