Zymogens , or proenzymes , are enzymes that aren't functioning yet because their action is infertile by a 'wrapper'. The 'wrapper' can be a link between two amino acids (the building blocks of proteins), like a piece of string keeping a box closed. Or it can be an further section of protein, like a jar lid.
