Why are enzymes important in a laundry detergent?
The enzymes used in laundry detergents act on materials that make up a variety of stains and soils so that these materials can be washed away more easily. These enzymes are named after the materials they can act upon, for example, proteases break down protein based stains, lipolases break down lipid (fat) based stains and amylases break down starches and other carbohydrate based stains (amyl is Greek for starch). Since one enzyme molecule can act on many substrate (i.e., soil) molecules, a small amount of enzyme added to a laundry detergent can provide a big cleaning benefit to the consumes.
