To answer the question, it is first necessary to understand what a polysaccharide is and what hydrolysis is.

The four "building blocks of life" is a commonly used phrase that refers to four kinds of small molecules that are essential in the creation and formation of larger macromolecules that exist in every living organism. These four molecules consist of simple sugars, fatty acids, amino acids, and nucleotides. "Poly-" means "many", and "saccharide" means "sugar," so as the name suggests, a polysaccharide is a type of sugar. In fact, it is a polymer made up of chains of sugar monomers, also known as monosaccharides, and monosaccharides are simple sugars such as glucose, fructose, and galactose. Sugars are important because they make up carbohydrates and store energy that is released through chemical reactions (Citovsky, Lecture #3).

Polysaccharides are formed during the process of condensation synthesis (Citovsky, Lecture #3). In order to synthesize, or create, a polysaccharide, a molecule of water is removed from two or more monosaccharide sub-units. In removing a hydrogen molecule from one sub-unit and a hydroxyl group from another sub-unit, an ether bond is formed between the two sub-unit. At the same time, a water molecule is created and released. Condensation synthesis is a process that stores energy in a larger molecule. In order to release this energy, it is necessary to break the larger molecule into small sub-components. The opposite of condensation synthesis is…
