An enzyme is form of protein that triggers chemical reactions and scientists typically name enzymes with the -ase suffix.
For example, the human body likes the sugar glucose but milk doesn’t contain glucose, it contains a different sugar called Lactose. (-ose is the suffix for sugars) So the small intestine produces an enzyme named Lact*ase* which chops Lact*ose* into two smaller sugars, glucose and galactose, which the body can use.
Like all proteins, enzymes are very sensitive to temperature and will be destroyed if heated up.
