Enzymes are biological molecules that are responsible for the many metabolic processes that sustain life. Enzymes need specific conditions in order for the reaction to occur. Temperature, pH level, and the shape and size of the substrate are all limiting factors. One of the most common digestive problems, lactose intolerance, is due to the absence of the key enzyme lactase. This enzyme is produced in the small intestine where it is secreted during digestion. While most mammals stop producing…

1. Wright PS. in 1984 stated that there is sufficient evidence available for use of soft liner but because of its inadequate physical properties the use of soft liner is limited. The objectives of the study were: 1. Clinical success of the available soft liner material and their retrospective study. 2. The collection and measurement of data relating to a group of wearing soft-lined mandibular dentures for edentulous patients. 3. A three year longitudinal study of the clinical success of both…

1. What is the difference between a monosaccharide and a disaccharide? Provide examples of each. Ans. Monosaccharide is a monomer that only consists one sugar but disaccharide has two. 2. Why is a sugar considered an organic compound? Ans. Because a compound that contains carbon is organic and the compound that doesn’t contain carbon is inorganic. 3. What are the three elements found in all sugars? Ans. Hydrogen, oxygen and carbon. Lipids 4. What are the two main parts of a lipid? Ans. Fatty…

I expected that pepsin will destroy the structure of gelatin protein, because the pepsin broke down the primary structure of the gelatin polypeptide into amino acid monomers. The hydrochloric acid (HCL) expected to affect the ability of amylase to digest starch, because as it is an acid it effects on the protein that makes it unraveled as it breaks down the secondary structure which it contains hydrogen bonds. As I have done to experiment one titled Digestion of Proteins by Pepsin. The result…

in the body and cause problems such as neurological diseases (Chacko et al, 2010). The third harmful effect that could possibly come from tea overconsumption is a decrease in iron bioavailability. As previously stated, tea contains the flavanol monomer catechin (Ruxton, 2008). Specifically in green tea, the catechins may have an attraction to iron and when consumed in the form of infusions, it can greatly decrease the iron bioavailability in ones diet (Chacko et al, 2010). As with any food…

Styrene (St, 99%) and methyl methacrylate (MMA, 99%) were obtained from Aldrich company. These monomers were first dried over calcium hydride, were purified by being passed through a column of basic alumina, and were distilled under reduced pressure. Ethyl 2-bromoisobutyrate (EBIB, 98%), copper (I) bromide (CuBr, 99%), copper (I) chloride (CuCl, 99%), and other chemical reagents were procured from Aldrich company and used as received. N-methylbis[2-(dodecylthio)ethyl]amine (SNS) was synthesized…

This could also lead to evolution, survival of the fittest, overpopulation and the extinction of others. Limiting factors can be many things like space, food, light and many other things. For Sunflowers and example that would lead to carrying capacity would be if all the organisms that consumed or killed the plant would be removed from its environment by an invasive species or environmental changes, then the Sunflowers would grow faster and closer to each other. This would cause space, water,…

There is a myth that states gum will stay in the human stomach for 7 years after being swallowed. However, studies have shown that this is in fact incorrect. Gum is very digestible and isn’t hard to break apart in the stomach unless consumed in very large quantities due to its sticky texture. In many incidents, swallowed gum passes through the digestive system as well as any other food. When somebody swallows gum the material is first taken down the esophagus (the first mushed food is called…

Today I will be writing about the protein that I was assigned which was Structural Protein. What is your protein? What are they used for? They are used to build structural components of the body such as bones and cartilage. They are mostly found in larger cells. These proteins provide keratins, actin and support. I will be talking about why this protein is important and what does it do. The shape of a protei determines its function and there also a lot of different levels. An example of the…

Determination of the gel-point of a resin via DMA testing and its use in a practical sense The DMA is used to determine the modulus values of the resin to associated temperatures and frequencies. The state of viscosity of the resin is also monitored through the evaluation of tan delta values. Gel-point of a resin implies that resin matrix has transformed into an elastic gel state and can no longer flow. The viscosity shows a sudden rise to extremely high values. The time at which this state is…
