! Affect of pH on Porcine Pancreatic Alpha-Amylase Activity Introduction Proteins function in a variety of different ways‚ and one of their fundamental tasks is to act as enzymes. Enzymes are extremely important in controlling reaction speed (by initiating and regulating biological activity)‚ cell communication‚ and growth. One particularly significant enzyme is amylase‚ which catalyzes the hydrolysis of alpha glycosidic linkages of amylose‚ starch components‚ and other oligosaccharides (Qian

temperature on amylase activity Design principle Background: Amylase activity products? (show the equation) Which factors will affect enzyme activity? How to study the rate of reaction? (e.g. rate of disappearance of substrates or rate of formation of products) Independent variable: temperature of reaction mixture or at which the enzymatic reaction occurs. It can be varied by setting water bath at different desired temperature ranging from 0oC to100oC). Dependent variable: rate of amylase activity

Treating Starch How are starch and cellulose treated to allow them to be used in yeast? Starches: · All potable alcohol and most fermentation industrial alcohol is currently made principally from grains. · Fermentation of starch from grain is somewhat more complex than fermentation of sugars because starch must first be converted to sugar and then to ethanol. · Starch is converted enzymatically to glucose either by diastase presents in sprouting grain or by fungal amylase. · The resulting

Introduction In the amylase lab‚ it was being tested if amylase‚ an enzyme found in saliva‚ would be denatured by being put in an acid or high temperatures. This lab is about denaturing amylase. It is tested by exposing it to pH and temperature changes. It is then mixed with Benedict’s solution‚ is a solution that changes color from blue to reddish brown when maltose is present. Amylase breaks starch into maltose‚ so is the amylase isn’t denatured‚ it should change colors. Amylase is an enzyme.

Enzymatic Activity of Salivary Amylase Abstract: Salivary amylase is an enzyme that can digest starch molecules and break them down to sugar molecules. In this experiment‚ the enzymatic activity and specificity of salivary amylase was examined depending on the changes in pH and temperature. In the first part of the experiment‚ the effect of temperature was determined‚ using constant temperature bath (4‚ room temp‚ 37‚ 50‚ 60‚ and 70°C). Having the room temp and 50°C as the highest and 37°C as infinite

Lab Report DIFFUSION AND THE EFFECT OF AMYLASE. Aim: We will interpret and explain the activity of an enzyme added to a solution. We will analyze reactions in different pH ranges. The starch solution will appear blue when mixed with iodine. But after mixing the enzyme amylase to the starch‚ the starches are broken down into simple sugars. Now‚ when the iodine is added‚ no color change exist. Instruments and materials used: 1.) Dialysis bags x2 2.)

Resistant starch (RS) is starch and starch degradation products that escape from digestion in the small intestine of healthy individuals.[1] Resistant starch is considered the third type of dietary fiber‚ as it can deliver some of the benefits of insoluble fiber and some of the benefits of soluble fiber. Some carbohydrates‚ such as sugars and most starch‚ are rapidly digested and absorbed as glucose into the body through the small intestine and subsequently used for short-term energy needs or stored
