What happens when lactase is added to lactose?
When enzymes are boiled they become denatured, meaning they lose their function because they lose their shape. Any change in temperature or pH other than the one they are accustomed to will disturb an enzyme's shape; simply reverse their environment changes, and they'll go back to their correct function.
What is the purpose of lactase?
When we use the "ase" ending for a chemical, especially in a biological sense, we are talking about an enzyme. Which is a protein that enables a chemical change not otherwise possible. It is a biological catalyst. Each single reaction that requires an enzyme is different so there is a different enzyme for every kind of reaction needed! We name the enzymes after the chemical they act on. Cellulase is a chemical produced by cows that acts on cellulose (see how similar they look?) which is the main structural component of plants. (By the way, the "ose" ending means a starch or a sugar, like glucose, fructose, amylose....) This allows the cow to digest tough plant material that humans would need to cook before eating (leaves) or cannot eat at all (hay.)
What is enzyme products?
Enzymes are complex proteins that exist in plants, animals and humans. In Biological terms enzymes function as biological catalysts (they make biological processes happen). In Chemistry catalysts often are metals like nickel or palladium (i.e the catalytic converter in your car). In the chemical industry catalysts are used to initiate, speed up or slow down a reaction. In Biological processes, enzymes or "bio-catalysts" are used to initiate a reaction or more simply put, to accomplish some kind of task. A good example is the enzyme "Lactase" which is used in the product called "Lactaid" (milk). All milk contains the sugar lactose which is said to cause digestive upset (lactose intolerance) in some people. The enzyme "Lactase" acts upon the lactose in milk and converts it to another sugar called galactose and one or two other harmless components rendering the milk "lactose free". LACTAID is REAL milk which has had lactose removed because of the action of the enzyme....Lactase was resonsible for the biological reaction that converted lactose to other sugars which do not cause digestive upset.
The pH at which an enzyme works best can vary greatly from one enzyme to the other?
true
What can change the way an enzyme acts?
Enzyme activity is affected by other molecules, temperature, chemical environment (e.g., pH), and the concentration of substrate and enzyme. Activators are molecules that encourage enzyme activity, and inhibitors are enzymes that decrease enzyme activity. Sometimes a cofactor is necessary for the enzyme to work.
What are some common enzymes?
Lactase is a common enzyme that breaks down lactose. Other common enzymes are diastase with aids in breaking down vegetable starch, sucrase which digests sugars, and protease which breaks down proteins
Why is the digestion of milk affected by lactose found in the stomach?
Are you talking about lactose intolerance? If so, people are lactose intolerant because they do not have the enzyme lactase that is use to digest the lactose. The gene that codes for the lactase cease to be express when they get older . Other people keep expressing the gene for their entire life.

Does the lactase enzyme hydrolyze substrates other than lactose?
Yes it does more than commonly believed. Lactose is just one of the Beta 1to4 "O" glycosides hydrolyzed by the lactase enzyme which is and incorrect nomenclature for the enzyme that is a Beta 1to4 "O" glycosidase. Many who clal them selves experts use the term lactase instead of Beta 1to4 "O" glycosidase due to flase thinking on the matter. Phlorizin, annatto, pectin, tomatine, salicin, various gums and solanine are but a few of those beta 1to4 "O" glycosides that the enzyme Beta 1to4 "O" glycosidase will hydrolyze. E.coli that lives on the proximal and distal sides of the eleocecal valve in humans will ferment, cleave, oxygen and carbon for the reducing end of the glycoside that is part of the aglycones above mentioned.

Can lactase act on any other sugar besides lactose?
It is possible for lactase to act on other sugars besides lactose. One specific sugar is the sucrose. However, most acts have problems digesting other forms of sugars.
What causes lactose intolerance?
lactose intolerance is caused by reduced or absent activity of lactase that prevents the splitting of lactose. it also occures when the small intestine does not produce enough enzyme called lactase. your body needs lactase to break down, or digest lactose.
How is fat removed from milk?
Lactose is present in milk. By substituting other food for milk like egg etc can remove lactose from our diet.More information:Lactose is the sugar that is present in all dairy products. It cannot be removed from those products. Instead, persons who are "lactose intolerant" must avoid all dairy products and all foods that contain dairy products as ingredients. Soy milk, almond milk, rice milk and coconut milk are all readily available at supermarkets and make excellent substitutes for dairy milk.

What does cysteine desulfurase catalyze?
From Wikipedia:In enzymology, a cysteine desulfurase (EC2.8.1.7) is an enzyme thatcatalyzesthe chemical reactionL-cysteine + [enzyme]-cysteine L-alanine + [enzyme]-S-sulfanylcysteine Thus, the two substrates of this enzyme are L-cysteine and [[[enzyme]-cysteine]], whereas its two products are L-alanine and [[[enzyme]-S-sulfanylcysteine]].This enzyme belongs to the family of transferases, specifically the sulfurtransferases, which transfer sulfur-containing groups. The systematic name of this enzyme class is L-cysteine:[enzyme cysteine] sulfurtransferase. Other names in common use include IscS, NIFS, NifS,SufS, and cysteine desulfurylase. This enzyme participates in thiamine metabolism.
The pH at which an enzyme works best can vary greatly from one enzyme to the other?
true
What might be an effect of the decrease in their production of lactase?
Their bodies cannot digest as much lactose as other people's bodies.
