Enzyme
This substance is called catalyst; and in living systems it is an enzyme.
The enzyme that causes the chemical breakdown of a substance is called a catalyst. Catalysts speed up chemical reactions by lowering the activation energy needed for the reaction to occur. This process allows the substance to be broken down into smaller components more efficiently.
