Research on an Enzyme

Regarding enzyme research, I studied the enzyme type of urease that I chose to use. Urease is an enzyme that catalyzes the hydrolysis of urea to ammonia and carbon dioxide. The reaction is as follows. (NH 2) 2 CO + 3 H 2 O 2 CO 2 + 2 NH 4 OH [IMAGE] It is a globular protein found in bacteria and higher plants discovered by James Sumner in 1926. It has a molecular weight of 480 kDa, an optimum pH of 4 and its enzyme specificity is urea and hydroxyurea.

The enzyme has a detoxification action - it may decompose toxic substances, discharge them, do not accumulate them, and may harm them. This is done by metabolic enzymes, but it is not a food enzyme, but the study showed that the enzymes we find in the food we eat may help our bodies do this . Interestingly, the test was done after the high temperature treatment of the barley extract. Researchers believe this will denature proteins and eliminate them. Detoxification ability was measured again, this time did not happen. This indicates that the antidote of barley is an enzyme and the enzyme is destroyed when heated. It also points out that the green barley extract is "alive" - ​​the enzyme is intact

When the enzyme is exposed to high temperature, the enzyme stops functioning. (There are exceptions such as enzymes of thermophilic bacteria). This is due to denaturation of the enzyme (expansion of the three-dimensional structure). At lower temperatures, the 3 - D structure is intact but there is the possibility that there is not enough energy to react. In this case, the enzyme is inactive, but it does not denature permanently. What is lactase? 2. Ask students about advice that helps patients manage lactose intolerance. This includes avoiding foods containing sugar lactose. Let students think about how hard it is to avoid particular foods. I will teach the students to think about the cause of lactose (lactase) breakdown. Ask students whether they think they can take lactase in some way and make them brainstorm

Lack of enzymes necessary to fully digest food. You may not have enough enzymes to digest a particular food. For example, if the amount of lactase is insufficient, the ability to digest lactose, the main sugar of dairy products, may be diminished. Lactose intolerance can cause fullness, cramping, diarrhea and excessive gas. Histamine toxicity Certain fish such as tuna and squid are not properly refrigerated, contain large amounts of bacteria and contain high levels of histamine and cause symptoms similar to food allergy. It is not an allergic reaction, but it is histamine toxicity or salmon poisoning.
