Easy Supply List, Fast Set Up

Enzymes in Biological Detergents: The Facts - Persil

What Are Enzymes in Biological Washing Powder? Most biological laundry detergents contain lipase and protease enzymes, both of which are found in the body. Lipases break down fats and oils, while proteases work to break down protein chains. Their ability to break down these compounds makes them excellent for stain removal.

Some enzymes are used commercially, for example, in the synthesis of antibiotics. Some household products use enzymes to speed up chemical reactions: enzymes in biological washing powders break down protein, starch or fat stains on clothes, and enzymes in meat tenderizer break down proteins into smaller molecules, making the meat easier to chew.

Working with enzymes final 080816 - University of Reading

Some dried enzymes, particularly those used in washing powders, are supplied as ‘prills’. These are small, crush-proof granules of cellulose with a small amount of dried enzyme at the centre — you can easily identify the spherical prills in biological washing powders by examining the product under a low-power binocular microscope or hand ...

Biosciences - Enzymes

An enzyme which would digest a protein will not digest starch, nor would a starch-digesting enzyme break down proteins. To see how an enzyme can break down proteins, and at the same time see if the claims of manufacturers of washing powders are true, try the following two experiments: Hole in the jelly. You will need:
