Hereditary fructose intolerance was first noticed and reported in an adult woman in 1956 by Chambers and Pratt (HFI). Chambers and Pratt observed that the woman started having faintness, nausea and abdominal pain after consuming fructose and sugar (HFI). However, those symptoms disappeared when the woman ate glucose instead (HFI). After a series of testings with different sugars, Chambers and Pratt believed that this woman was “idiosyncrasy to fructose”, but they never thought it would be…

Health and wellness are essential for optimal well-being. According to the World Health Organization health and wellness is, “a state of complete physical, mental, and social well-being and not merely the absence of disease and infirmity” (Edlin & Golanty, 4). Health affects every aspect of life. Authors of Health and Wellness Edlin and Golanty state, “Health is not static, it is a dynamic process that takes into account all the decisions we make daily, such as the foods we eat and the amounts…

The purpose of Activity 1 of this lab is to understand how cell transportation works, The purpose of the second part is to explore semipermeable membranes. The purpose of Activity 3 is to explore how the size of a cell affects cell transportation. Background All cells are surrounded by a barrier called the cell membrane. It regulates what enters and leaves the cell, and also protects and supports the cell. Cell membranes are semipermeable, meaning it doesn’t allow all molecules to pass through…

“Free sugars refer to monosaccharides (such as glucose, fructose) and disaccharides (such as sucrose or table sugar) added to food and drinks… and sugars naturally present in honey, syrups, fruit juices and fruit concentrates” (WHO). Despite this report, sugar lobbyists recommend 25 percent which is two and half times the scientific…

When we first were signing up to choose our topics, I chose baking because I like to simply bake. I thought that there could be some chemistry involved due to heat in the oven changing food from liquid to solid. I was so wrong. Even though the oven and heat portion plays a major factor, a good portion of the real chemistry lies in the ingredients we use to make such delicious dessert treats and our different breads. From the ten different sources I looked up previously, for the Annotated…

PURPOSE We used chemical indicators to identify possible sugar, starch, protein, and lipids present within two common food items as well as the dead Anna Garcia’s stomach contents. HYPOTHESIS If Anna ate foods like pizza, ice cream, and Oreo cookies like she said on her food log, then her stomach contents should react with the chemical indicators for glucose, maybe starch due to the pizza. INTRODUCTION The experiment considers the types of macromolecules within each piece of food. Each type…

It is a disaccharide with a molecular structure made up of 12 atoms of carbon, 22 atoms of hydrogen, and 11 atoms of oxygen (C12H22O11). As stated before it is a compound of fructose (C6H12O6) and glucose (C6H12O6) both of which are monosaccharides. Its main use is…

processing. Starch consists of amylose and amylopectin. They are built of glucose molecules, the only difference is the linkage between this molecules. Starch processing is used to convert starch originating from maize, wheat or potatoes into disaccharides or monosaccharides. A very big area of operation is the production of High Fructose Corn Syrup (High Fructose Corn Syrup). Three different enzymes are used in the processing of corn to the HFCS end product. The first step in HFCS production,…

All cells are derived from pre-existing cells - through the process of meiosis and mitosis 4. In a multicellular organism, the activity of the entire organism depends on the total activity of its independent cells 3 Significance of technological advances to developments in the cell theory Assess the impact of technology including the development of the microscope on the development of the cell theory The development of cell theory has been heavily impacted by the improvement of technology. The…

would denature at a pH of 2 because they belong in an alkaline environment with a pH of 8 and not an acidic environment with pH of 2. Lactase is a great example of this. Lactase is the enzyme that catabolizes (breaks down) the sugar lactose (a disaccharide) into the two monosaccharides, galactose and glucose. Lactase is mostly found in the small intestine, where the pH is around 7. Therefore it is reasonable to hypothesize that human lactase is optimally active at 37 ˚C and at a pH of…
