Write a "word equation" to describe the chemical reaction that occurs when pineapple is mixed with the gelatin.

There is an enzyme named bromelain from pineapple that can digest protein into amino acids. The bromelain enzyme from pineapple will digest the collagen protein from gelatin. This will make the collagen protein which was not soluble into water become smaller amino acid that was soluble in water. The gelatine will look like melting.
