Lactase

to diagnose the disease is a blood test for gluten antibodies, or a biopsy of the small bowel to assess if any damage has been done to the gut. Skin biopsies might also be taken. Lactose intolerance is caused by the body not producing enough lactase. Lactase is an enzyme secreted in the small intestine that digests substances containing lactose. If lactose is consumed, symptoms like stomach bloating,…

Sarah Gourgues BIO LAB 1130.036 December 1, 2016 They call me DJ Enzyme because I 'm always breaking it down Abstract: Although protein function is thought to depend on the dynamics of the molecule and its environment contribute to catalytic mechanisms. The increase and decrease of temperatures affected the rate of reaction. In nature, organisms adjust the conditions of their enzymes to produce an optimum rate of reaction, where necessary, may have enzymes which are adapted to function well…

According to the USDA ‘’The average American wolfs down 36 pounds of cheese and 24 pounds of ice cream or dairy products. You wash all that down with 200 pounds of milk and cream.’’ (Fowler) Even though dairy is tasty it has many negative factors. From causing acne to even causing cancers dairy is an unknown threat to health. Any dairy product can cause acne to trigger. At Dartmouth Medical School a group did some research. In their findings was milk has testosterone-like hormones which can…

Lucy also consume carbohydrates such as berries and oranges, (the process in which the food moves down from the mouth to the rectum is the same as above.) it is first digested mechanically by chewing. The digestion of carbohydrates begins in the mouth by salivary enzyme, amylase, the fruits starches are digested into maltose and disaccharide. As the food travels through the esophagus to the stomach, no significant digestion of carbohydrates takes place as the HCl in the stomach stops amylase…

Citrate: The citrate test gave a positive result, showing a dark blue color in the tube, caused by the alkaline conditions present, which is caused by the bacteria’s ability to utilize the citric acid present in the citrate slant. The positive result confirms the presecnce of the citrase enzyme. H2S Production: The H2S test yielded a positive result, giving rise to a black precipitate created by iron and H2S combining. Proving the presence of the desulfurase enzyme. Indole: The indole test…

they are lactose intolerant. According to “Lactose Intolerance and Malabsorption”, Lactose is found in the milk of most mammals in concentrations ranging up to 7 percent. It is digested in the small intestine by lactase, which is anchored to the membrane by amino acids. In most mammals, lactase activity is high during the perinatal period but declines by about 90 percent after weaning” (par. 2). Having this health issues might cause an upset stomach, problems with using the bathroom, or being…

Basic Biology The documents I attached include a lab report, worksheets, notes and one exam. My most memorable experiences in biology were in the lab. I got to test the effectiveness of lactase drops when exposed to solutions containing different pH or temperatures. My results indicated that the lactase enzyme had the optimal catalytic activity at temperatures similar to those found in the human stomach; however, the low pH in the stomach–ranging from 2 to 5– rendered the drops ineffective…

that. Human LCT codes for the production of lactase, a much stronger version of the enzyme that allows for humans to digest the milk of any type of mammal. The evolution of this gene actually happened twice separately in human history. European and African descendants actually developed this stronger gene independently to each other in human history. However, humans of Asian and Latin American descent never developed as strong of a gene for lactase, which makes them much more likely to be…

Food allergies and intolerances are more common than you think. Food intolerances relate to the inability to digest certain foods. A food allergy is when your body has an adverse immune response to a specific food. Food intolerances usually come on gradually where as food allergies are usually more sudden. Some people with a food intolerance may be able to eat small amounts of the food whereas with a food allergy an allergic reaction can be triggered by even a small amount of the food. A food…

Crohn’s disease is defined as a “transmural inflammatory process.”1 Crohn’s disease is one of the two forms of inflammatory bowel disease.2 Crohn’s disease most commonly affects the end of the ileum, which is the last part of the small intestine. Although, it can occur anywhere throughout the entirety of the gastrointestinal tract.1 Typically, there are areas of the gastrointestinal tract that are normal, but these segments are separated by areas of the gastrointestinal tract that have damage.…
