Lactose Intolerance And Its Effects On The Body

Lactase is an enzyme located in the mammalian small intestine that breaks down lactose into sugars, glucose and galactose. It is a necessary enzyme in order to digest lactose, a milk sugar, which cannot be absorbed directly.

-Lactose Maldigestion: reduced digestion of lactose due to low lactase activity that subsequently results in MALABSORBTION of lactose; it may be asymptomatic.

If someone is lactose intolerant, that means that they are lacking the enzyme lactase, so the lactose does not get broken down into galactose and glucose. If lactose goes undigested it creates many problems. It causes dehydrations because water and electrolytes get pulled into the intestines by the lactose, which acts like an osmotic agent. The result of the increased amount of lactose would be diarrhea, bloating, and gassiness. Although being lactose intolerant seems to be abnormal, it is actually natural. The production of the enzyme, lactase, is a mutation of the LTC gene, it allows us to produce lactase as adults. In all other mammals lactase is produced during infancy but not during adulthood.

S lactose intolerance, mouth ulcers, and IBS (irritable bowel syndrome). Damage to your small intestine may cause you to experience abdominal pain and diarrhea after eating lactose-containing dairy products, even though they don't contain gluten ("Celiac Disease," n.d.). Mouth ulcers become apparent as a late sign and symptom of celiac disease. Celiac disease has symptoms similar to other digestive disorders, such as irritable bowel syndrome, gastric ulcers, Crohn's disease, parasite infections and anemia ("Celiac Disease,"

Lactose intolerance is a condition that many people have. It occurs when the small intestine is unable to break down sugars that are produced in milk and other dairy

b. If I consume dairy when I have lactose intolerance, a series of unpleasant side effects which includes intestinal cramps, bloating, unpleasant gases and diarrhea would happen.

Hereditary fructose intolerance is passed down by both parents have to have it to inherit it.

Module four discussed lactose intolerance and dumping syndrome in great detail, then briefly explained other disorders of the GI tract and pancreases. Lactose intolerance occurs when the body can no longer efficiently digest lactose result in bloating, cramping, and sever diarrhea. Lactose is not directly absorbed by the body, so lactase has to break it down into glucose and galactose. The breakdown of lactose occurs in the last part of the small intestine, but if this does not occur then lactose will move to the colon causing an osmotic effect. The osmotic effect will causes water to diffuse into the colon through capillaries of the intestinal tissue. Colonic bacteria will start to metabolize lactose, and produce gases such as carbon dioxide, methane and hydrogen gas.

Congenital lactase deficiency: is extremely rare, caused by an enzyme defect the prevents lactase production from birth. Infants with this deficiency cannot digest lactose, and breast milk, from birth. Babies born with genetic defect have high death rates, though that has decreased with soybean-derived infant formulas. This deficiency only comes from genes inherited from

How does one’s body able to break down enzymes? What happens is that the small intestine produces an enzyme known to be called, lactase. Lactase then breaks down lactose into more simplified forms of sugar (which are glucose and galactose), our body is then able to absorb the broken down, simplified sugars into our

Abstract Lactose is recognised as a disaccharide; in other words, it consists of glucose and galactose and two smaller sugars bound altogether with a covalent bond. In the form described, lactose is indigestible by us humans; therefore it must be hydrolysed, or broken down, for our body in order to process it. Lactase catalyses this process by decreasing the energy required for hydrolysis to happen. Lactase is a digestive enzyme that catalyses the breakdown of lactose, a sugar found in milk.

Lactase breaks down lactose in milk therefore the glucose would be found in the lactose. The independent variable in this lab was the lactaid, milk, water, glucose, and the lactaid and milk combined together. The dependent variable was the positive or negative reaction the experiment resulted in. The methods include using seven test tubes containing crushed lactase pills and drops of different levels of pH in each tube, including a controlled tube, and different temperature

The experience of lactose intolerance have occurred to a number of individuals for a lengthy number of centuries. Lactose intolerance can happen when one loses their ability to produce lactase, as they grow older, meaning that they struggle to consume milk. On the other hand, infants are capable to produce a great deal of lactase since they can drink from their mother’s milk. The term lactase is defined as an enzyme that is capable of breaking down the disaccharide sugar lactose into monosaccharides. Because of lactose intolerance, nature was able to naturally select humans who are affected by lactose. In reference to history, back around 7,500 years ago in Central Europe, the idea of using cow’s milk as a beverage, spread. Incidentally, this

They would eventually have a decreased frequency in individuals who are lactose tolerant since there would be lower selective pressure and therefore lower demand of that trait since evolutionary there would be no favorability to keep the ability to drink milk. This would lead to increased intolerance in subsequent generations due to availability of different food and the cessation of dairy consumption. There is also a possibility that gene flow or other populations moving, mutation or genetic drift, affecting the allele frequencies allele frequencies of lactase

Lactose intolerance is a common digestive condition where the body is unable to digest lactose, a natural sugar that is found in milk and dairy products. During a normal digestion, lactose is broken down by an enzyme called lactase into glucose and galactose. People with lactose intolerance do not produce enough of lactase; so lactose stays in the digestive system where the gut bacteria resulting in the production of gases ferment it. The lack of lactase can be variable, permanent or transient, particularly in young children who often develop a temporary lactose intolerance concomitantly with an infection of the digestive tract. While some lactose intolerance individuals are unable to digest any milk product at all, some are able to tolerate
