In chemistry, what is defined as a ‘substrate’?

In the context of chemistry, a substrate specifically refers to a molecule or substance that is acted upon by an enzyme or a catalyst in a chemical reaction. Substrates are crucial in biochemical reactions, where they bind to enzymes to undergo transformation, resulting in products. This concept is fundamental in understanding metabolic pathways and enzymatic activity, as the substrate’s interaction with the enzyme leads to the creation of new substances.

The role of the substrate is central since it is the entity that undergoes change during the reaction, facilitating the biochemical process. This definition aligns perfectly with the general understanding of substrates in a variety of chemical contexts, reinforcing its importance in both theoretical and practical aspects of chemistry.
