Polysaccharide
Generally in an enzyme-catalyzed reaction, the reactant is called the substrate, which in association with the enzyme forms the product.
The region where reactants bind to an enzyme during a biochemical reaction is called the active site. It is a specific region on the enzyme where the substrate binds, forming an enzyme-substrate complex that leads to the catalysis of the reaction.

Lactose intolerance is the inability to efficiently convert lactose into glucose and galactose, a reaction catalyzed by the enzyme lactase. (A rule of thumb for enzyme nomenclature is that many enzyme names typically take most of the name of their substrate and slap an "-ase" at the end.)
Substrates
Reactants are substances that can combine in a chemical reaction.
Irreversible :D
The substances at the start of a chemical reaction are known as reactants. Reactants are the molecules or compounds that undergo a chemical change during the reaction. They are typically written on the left side of a chemical equation, while the products of the reaction are written on the right side. The reactants are consumed during the reaction to form the products.
In a chemical reaction, the starting materials are called the reactants.
Another name for reactants is substrates. These are the starting materials in a chemical reaction that are transformed into products.
