Enzyme Lab

Enzymes Abstract lactase is an enzyme prep ar in the small bowel that pass ons mass lactoase into the products ga milk incision and glucose. Lactase can be purchased in some contour lines and one form is the pill form in which mint take when they are milk slit intolerant. These people lack the enzyme lactase, and cannot push through take shoot down the sugar lactose into its component parts. Lactose, the sugar found in milk, is a disaccharide composed of glucose and galactose. sucrose will be likewise used in the labs. sucrose is a principle remand sugar and is also a disaccharide composed of laevulose and glucose. Although lactose is similar to sucrose, the enzyme lactase will plainly break down moreover its substratum, lactose, because of the shape of the sugar. Objectives/ Introduction Enzymes are protein molecules that barrack up a chemical reaction. Enzymes are specific; they only work with certain substrates. Substrates are the reactants in an e nzymatic reaction. prohibited group conducted twain labs which examine how specific an enzyme is to a substrate and how much environmental factors affect enzyme reactions. Lactase is the enzyme that breaks down lactose into galactose and glucose. Since theyre both a six sided sugar, lactase can only break down lactose. Lactose is the sugar found in milk, and sucrose is an ordinary table sugar.

Sucrose is a disaccharide composed of glucose and fructose. Fructose is a five sided sugar, so lactase cannot break down sucrose. Temperature and pH are twain environmental factors that will be used in the fit for part of the lab. One of the enzymes is denatured, m! eaning it was boiled for twenty legal proceeding in hot water. The purpose of this experiment is to examine the specificity of the enzyme lactase to specific substrate lactose. Our group predicted that if lactase breaks down lactose then glucose and another sugar will be the approach result for the first part. For the second part we predicted that if the pH is 4 then the lactase will be getting a larger amount of glucose and if...If you want to get a great essay, order it on our website: OrderCustomPaper.com
