Madam Chan is a 72 years old lady who suffered from some physical condition recently. She usually be alone in her home and cannot buy food from markets and cook them as usual due to not being able to go up and down stair which is the only method for her to go out and back home. With the reason of it‚ her home is full of tin food‚ instant food‚ preserved food as well as the left-over food. Besides diminishing of life-space due to reduced mobility‚ the nutritional problem is also one of the concern

4446 Exam 2 Study Guide Lactose Mal Digestion/ Malabsorption 1. What are the products of lactose digestion? -The products of lactose digestion are glucose and galactose. 2. What is lactase deficiency? -Lactase deficiency is a deficiency in the enzyme that breaks down lactose. The causes of lactase deficiency include congenital defects‚ secondary lactase deficiency‚ and primary (acquired). 3. Define lactose maldigestion‚ identify the potential etiologies of lactose maldigestion‚ and describe

TITLE: Solubility and Thermodynamics PURPOSE: The purpose of the lab was to determine the thermodynamics variables of ∆H‚ ∆S‚ and ∆G for the dissolution reaction of potassium nitrate in water. The solubility of potassium nitrate in mol/L was measured over a range of various temperatures by finding out at what temperature crystallization began for solutions of different molarities. Then‚ the equilibrium constant was calculated and a graphical relationship between the natural logarithm of the

molecular compound lactose. Description: Lactase is primarily a digestive enzyme that is produced by specialized cells that line the lumen of the small intestine. Lactase ’s primary function is to break down a sugar called lactose. Lactose is a sugar that is found in milk as well as many other dairy products. Since lactose is a very large sugar‚ it cannot be absorbed naturally by the human body. In order to metabolize this form of sugar‚ your body needs lactase to break down lactose into two smaller

Milestone Assignment By Sam Sherman Heartburn and Lactose Intolerance Heartburn: Heartburn is a burning feeling in the lower chest. It affects taste in the mouth. Sour and bitter tastes occur frequently. Heartburn usually occurs after eating a big meal or while lying down. This feeling can last for a few minutes or a few hours. There are causes and risk factors that come into play. When you eat‚ food passes from your mouth down a tube called the esophagus. To enter the stomach‚ food has to pass

The milk consumption of the Filipinos is 70‚000 MT in the year of 2011. In recent statistics‚ it shows that in Asian countries‚ most people either have lactose intolerance or milk allergy. Lactose intolerance is the inability to digest lactose‚ a sugar found in milk. This is caused by the lack of lactase‚ the enzyme required to breakdown lactose in the digestive system. Milk allergy is an adverse immune reaction to one or more of the constituents of milk from any animal‚ most commonly “alpha S1-casein”

Introduction In this task I will investigate how the enzyme lactase breaks down the disaccharide lactose into monosaccharides‚ which are glucose and galactose. The main aim will be to get lactose – free milk as milk contains lactose. When we drink milk we need lactase (enzyme) to break down the lactose‚ which is contained by the milk. Once I have created my own method of enzyme immobilisation of lactose using lactase I will then construct a bioreactor. I have looked at and researched on the Internet

almond milk is driven by its increasing popularity among consumers. These beverages are a part of the traditional diet in the Asia-Pacific region. The main driver of the market is the health benefit of dairy alternatives for consumers who suffer from lactose intolerance‚ milk allergy‚ etc. Accurate marketing practices and the apt knowledge dissemination programs to educate consumers are foreseen as the biggest opportunities in the market. The dairy alternative beverage market is projected to reach

boiled until it coagulates. It was filtered and reserved for part B. The coagulum was divided into two portions and the Biuret test and heating was performed. B. The filtrate from III.A was used for the other tests. a.> Test for lactose. 5 drops of the filtrate was added with 3 ml Benedicts’ reagent. It was heated in a water bath. The results were noted. b.> Test for calcium ions. 1ml of the filtrate was added with 1 ml of (NH4)2C2O4 solution. c.> Test for phosphate
