    m 20 March 2015 Hypolactasia Lactose intolerance, also known as hypolactasia, has become a huge epidemic over the years. This is a result of a genetically determined decline in the activity of lactase that begins in early childhood. Many people have suffered from this inability to digest lactose, which is found in milk and other dairy products. People who are lactose intolerant only have symptoms occur when they have dairy/milk products. These symptoms include bloating, cramps in the lower abdominal area, stomach growls, gas, diarrhea, and/or vomiting. In article by Leena Seppo, Tuula Tuure, Riitta Korpela, Irma Jarvela, Heli Rasinpera, and Timo Sahi called, “Can primary hypolactasia manifest itself after the age of 20 years? A two-decade…

    Lactose Intolerance Lactose intolerance is a metabolic issue when the body produces insufficient lactase enzymes in the small intestines to digest the lactose sugar found in dairy products. Fortunately, this condition doesn’t cause any physical damage, however, it can produce symptoms such as abdominal gas, bloating, diarrhea, pain, and nausea. The severity of these symptoms is directly proportional a person’s lactose intolerance, and the amount of lactose they consume. What is Lactose and How…

    Rodrigues Bio 345 June 22, 2019 Lactose Tolerance and Human Evolution In the HHMI movie by Dr. Sarah A. Tishkoff, she explains how lactase persistence is an example of human adaption. Throughout her lecture she goes into detail about how lactose tolerance and lactose intolerance came to be, and how this adaption developed. In this paper I am going to address five specific questions that explain the adaption of lactose tolerance/intolerance in adult humans. The proximate mechanism that…

    Lactose is a sugar found in milk and milk products. Lactase Is an enzyme found in the small intestine that breaks down lactose into simple sugars such as glucose. The substrate has to fight to bind with the enzyme lactase. The inhibitor tries to attach to the lactase and slow down the chemical reaction while the substrate does the opposite. The substrate increases the rate of the chemical reaction, this chemical reaction breaks down the lactose into sugars. This chemical reaction is imperative…

    In this case, we added the lactase solution (independent variable) to milk. The dependent variable of this experiment was milk. In this case, the amount of glucose produced in the milk (dependent variable) was measured. The constants of this experiment were the amounts of liquids (10 mL of milk and 1 mL of lactase), time to break down before testing (6 minutes), temperature, and type of container (test tube). The purpose of the experiment was to test the effect of the enzyme lactase on the milk…

    Americans are considered to be lactose intolerant. Lactose intolerance is a common chronic digestive disorder in which a person’s intestinal tract lacks the ability to make lactase. It results from a drop in or disruption of the production of lactase in the small intestine. The small intestine is a primary part of the digestive system, and is the longest part of the gastrointestinal tract and makes up about three quarters of the digestive system. It is a hollow tube like organ that connects to…

    The Eymology Of Lactose

    • 406 Words
    • 2 Pages

    The molecule Lactose has the biological function of being used as energy in the body, like a carbohydrate. When you consume it, you break it down into glucose then galactose. You use enzymes to break it into these two parts, which releases energy throughout the body. You can use other carbohydrates without an ill effect, therefore you don’t really need to use lactose. The common name is Lactose, the IUPAC name is β-D-galactopyranosyl-(1→4)-D-glucose. Its formula is C12H22O11. The etymology of…

    Introduction: Lactose intolerance is one of the most common conditions, which affects millions of people. People with this condition do not produce the lactase enzyme which metabolizes the sugar on their own therefore they are unable to break down the Lactose which is sugar that is found in milk. Lactase is an enzyme found specifically in milk sugar “Lactose”. It breaks down the lactose into monosaccharaides, galactose and glucose. The Lactase enzyme can be used to aid people with this…
