scale Enzyme applications 1. Detergents Bacterial proteinases are still the most important detergent enzymes. Lipases decompose fats into more water-soluble compounds. Amylases are used in detergents to remove starch based stains. 2. Starch hydrolysis and fructose production The use of starch degrading enzymes was the first large scale application of microbial enzymes in food industry. Mainly two enzymes carry out conversion of starch to glucose: alpha-amylase and fungal enzymes. Fructose

There are many reasons why enzymes have such a high specificity. The first variable is an enzyme’s primary structure. A primary structure is just a combination of amino acids. There are twenty different amino acids that the primary structure can be created from. Every enzyme has a different order that the acids are placed in and each one has a different number or amino acids. The slightest change in this structure can affect a protein’s conformation and function. The secondary structure is a regular

experiment shows the effects of changing the pH level has on Catalase. As predicted‚ the farther away the pH levels got from the optimum pH (7.2)‚ the lower the reaction rate. At a pH of 7.2‚ the foam of the reaction measures 6cm. At a ph of 3 it measures 2.5 cm‚ at a pH of 5 it measures 2.75 cm‚ at ph 9 it measures 2.3 and at 11cm it measures 2cm. pH measures the hydrogen ion concentration of a substrate. By changing the pH of the catalase‚ the enzyme was denatured. Denaturing is the result of altering

Being lactose intolerant means that people cannot digest lactose products properly. This condition effects people at all different levels. The symptoms being shown with this are bloating‚ diarrhea‚ gas‚ and nausea. This condition is due to the large intestine not being able to break down the lactose into glucose‚ because of the lack of enzyme lactase. In order for the large intestine to work properly it needs certain dairy products such as yogurt to help with digestion. When a person id lactose intolerant

pH pH means Power of Hydrogen or Potential of Hydrogen. pH is a scale of acidity from 0 to 14. It tells how acidic or alkaline a substance is. More acidic solutions have lower pH. More alkaline solutions have higher pH. Substances which are not acidic or alkaline i.e neutral usually have a pH of around 7. Acids have a pH less than 7. Alkalis have a pH greater than 7. There are a lot of ways for finding the pH of something. One way is to use litmus paper. The pH paper is able to tell how strong

experiment: Effect of pH on enzymatic activity Background Information: Trypsin is a protease which conducts hydrolysis forming peptides. It is an enzyme which is secreted by the pancreas into the small intestine and works best in an alkaline environment. Egg white is used in this practical as it is found to contain the protein/ enzyme trypsin. pH is the measure of the amount of H+ ions in a solution‚ these ions affect the shape of the enzyme. Hypothesis: That as pH increases‚ the rate of

1.7 Factors that affect the activity of an enzyme It is important when working with enzymes to understand basic enzymatic theory behind them when selecting conditions to measure the activity of the enzymes. The factors that are known to affect the concentration of enzymes are temperature‚ pH‚ concentration of enzyme‚ concentration of substrate‚ buffer type and concentration‚ the presence of any inhibitors and cofactors (Worthington-biochem.com). 1.7.1. Temperature With most catalysed reactions‚

Environment Can Effect Enzymes Introduction: In a chemical reaction there sometimes can be a catalyst present known as an enzyme. An enzyme is a protein that speeds up a chemical reaction by lowering the amount of activation energy required to start the reaction. By lowering the activation energy‚ more of the substrate is able to participate in the reaction‚ speeding it up. Enzymes are substrate specific. The substrate is what the enzyme bonds to. That is to say that enzyme A will only react with

How Enzymes Work In Different Environments By Sarah Smith Biology1111 October 20‚ 2011 Lab Partner: Nellie Greer ABSTRACT Peroxidase is an enzyme found in potatoes that catalyzes the breakdown of hydrogen peroxide‚ H2O2‚ into O2 gas and water. We examined the different pH environments that can affect the enzyme activity during the breakdown of H2O2. In order to do this‚ we added different levels of pH‚ low‚ medium‚ and high‚ into different test tubes with the enzyme and H2O2‚
