WebbProtein digestion is represented in this experiment by the fact that when the proteins in the milk are digested, the solution turns from opaque cloudy white to a see-through solution. In an enzyme controlled reaction such as that of protein digestion in milk, an increase in the concentration of enzyme will lead to an increased reaction rate. WebbAfter the enzyme had been isolated, the effect of temperature and time on the enzyme’s activity could then be tested. Three test tubes were labeled with the appropriate temperatures: 40°C, 60°C, and 80°C. 1 mL of 0 M citrate buffer, 1 mL of substrate (1 mM p-nitrophenyl glucopyranoside or pNPGP), and 0 mL of dH 2 O were added to each tube …

The following personal hygiene guidelines are recommended to minimize exposure: Hands should be washed with water and mild soap after contact with enzyme materials. WebbIntroduction In today's laundry detergents, enzymes such as proteases and amylases are some of the active ingredients. In the U.S., about 50% of liquid detergents, 25% of powder detergents, and almost all powdered bleach additives now contain enzymes to help break down stains that are otherwise hard to remove with conventional surfactants alone.
