Comparison of Washing Powders: Blood on Clothes- biological washing powder biology topics ,Biological washing power contains the enzymes for the removal of stains, however washing powders usually only contain one enzyme but some powders can contain all three. Whereas no enzymes are included in the non biological powder, this can potentially make stain removal more difficult. Literature Review4. Enzymes - National 4 BiologyWe know which washing powders have these enzymes added because they are called “biological washing powders”. The enzymes are added because of their ability to speed up breaking down reactions. Enzymes are added which help break down fat and protein stains on our clothes and make these stains easier to remove.
Why do think then that biological washing powders only work at low temperatures? D. & F. The bonds which hold a protein's shape are quite sensitive to changes in pH. At the optimum pH (E) the bonds are creating the right active site shape to allow the enzymes to catalyse the reaction. However, as the pH is further from this optimum, fewer and ...
(b) Some students wanted to find the optimum (best) temperature for using biological washing powder. A Petri dish was filled with agar jelly containing starch. A circular hole was cut into the centre of the agar. A solution of the biological washing powder was put into the hole. The Petri dish was incubated at 10 °C for 10 hours.
Enzymes are biological _____. They speed up _____ without being changed themselves. A substrate binds to a region of the enzyme called the _____ _____. ... Biological washing powders often contain protease enzymes. Devise an experiment to test the effect of pH on the activity of biological washing powder. ...
One common use in the home is in biological washing powders. These contain amylase, lipases and proteases and break down any stains that contain carbohydrate, fat and protein. They therefore digest “biological” stains from the clothes. Since enzymes work at a low temperature this saves electricity and makes them good for delicate fabrics.

Because stains are made of different types of molecules, a range of enzymes are needed to break them down. Proteases break down proteins, so are good for blood, egg, gravy, and other protein stains. Amylases break down starches, and lipases break down fats and grease. Washing powders usually only contain one type of enzyme, though some have two or all three.
Biological washing powders contain protease and lipase to remove protein stains and fat /grease from clothes. The enzymes break down proteins or fats on the fabric, forming water-soluble substances that can be washed away. Example: Blood contain the red protein Haemoglobin (Hb). The Proteases in biological washing powder break Hb molecules into ...

Because they feature enzymes biological detergents can work well at a wide range of temperatures which is especially useful for colder washes. The enzymes are very useful because they break down tough stains very easily, stains that are notoriously tricky like blood and sweat are more easy to wash away with biological detergent.
