Starch can be hydrolyzed into simpler carbohydrates by acids‚ various enzymes‚ or a combination of the two. The resulting fragments are known as dextrins. The extent of conversion is typically quantified by dextrose equivalent (DE)‚ which is roughly the fraction of the glycosidic bonds in starch that have been broken. These starch sugars are by far the most common starch based food ingredient and are used as sweetener in many drinks and foods. They include: Maltodextrin‚ a lightly hydrolyzed (DE

The Catecholase-Catalyzed Reaction Abstract This paper describes an experiment to determine ……………. Introduction Enzymes are made from proteins. They are biological catalysts that speed up the rate of chemical reaction by lowering the activation energy of the reaction. Enzymes are precise and catalyze only detailed reaction. Specificity is an outcome of active site of enzyme that acts on the substrate. Catecholase‚ which catalyzes a reaction in which catechol‚ then catechol becomes

group and this write-up is entirely my own creative work.” X________________________________________ Introduction Enzymes are protein molecules that speed up the rate of reactions by reducing the activation energy of a reaction. They act as catalysts in reactions‚ increasing the rate at which a normally spontaneous reaction occurs without being changed themselves. Without enzymes‚ life would not exist because they are vital to the normal function of cellular processes. In an enzymatic reaction

Abstract The abstract‚ although it comes first logistically‚ always should be written last. It needs to be written last because it is the essence of your report‚ drawing information from all of the other sections of the report. It explains why the experiment was performed and what conclusions were drawn from the results obtained. A general guideline for an abstract has five sections or areas of focus: why the experiment was conducted; the problem being addressed; what methods were used to solve

Studying the Rate of Reaction of catechol oxidase and how it affects pH levels Introduction: In this lab‚ we studied the activity of an enzyme that is found in fruits and vegetables called catecholase or catechol oxidase. An enzyme is a protein molecule that is a catalyst. Catechol oxidase is the enzyme in fruits and vegetables that turns them that undesirable brownish color; also commonly referred to as bruising or bruised.

Lactase is an enzyme that splits up the disaccharide lactose into monosaccharides glucose and galactose‚ but its function diminishes with age resulting in a wide use of lactase supplements. This enzyme functions under specific conditions‚ so we investigated the effect different salt concentrations have on the enzyme activity. Serial dilutions were performed to prepare a lactase solution as well as twenty percent‚ fifteen percent‚ and five percent concentrations of NaCl. Three different treatments

environmental factors of enzymes were tested in lab. The changing of pH‚ substrate concentrations‚ temperature‚ and an inhibitor (NaCl) and the effects it hade on the enzyme turnip peroxidase. Enzymes are biological catalysts which increase reaction rates by lowering the activation energies of substrates. A substrate is a reactant that interacts with the enzyme. The enzyme and substrate can be viewed as the recently discovered "induced fit model"‚ which suggests enzymes are flexible and dynamic things
