They are certain proteins that speed up various chemical processes within in an organism, or they are what actually enables them. In cleaning applications, enzymes support the decomposition or "dissolving" of organic contaminants, and are therefore used as an essential component of cleaning and stain removal products. Enzymes are highly effective proteins, which are able to even perform functions in small quantities and at low temperatures. Depending on their effect there is a distinction between: amylase, cellulase, lipases and proteases.
