BIS 102 Dr. Monfared
Elastase and How It’s Giving You Wrinkles
Enzymes encompass our lives by carrying out various processes that have both negative and positive effects on our bodies, and the aging of our skin is no exception. In BIS 102, Dr. Monfared emphasizes the importance of enzymes and its varied functions that make biological processes achievable. As a result, these biological catalysts allow life to take place by reducing the activation energy needed for chemical processes, such as the breakdown of sugars and proteins. While a majority of the catalyzed reactions are beneficial for our wellbeing, others are disadvantageous especially in older age. As individuals progressively age, enzymes do more than just carry out necessary reactions; they also start to degrade various regions of our body, one

As the enzyme continually degrades elastin, one simple solution is to increase the amount of the protein to catch up with its breakdown. This solution can be achieved through the topical application of tropoelastin. Tropoelastin is an immature form of elastin that is penetrated into the dermis and matured over time. (3) With the addition of more elastin, the skin is able to revert its indentations back into its resilient state. However, the continual application of elastin is inefficient. Thus, a better alternative is the introduction of inhibitors of elastase. Similarly to tropoelastin, the inhibitors can also be applied topically through doxycycline hyclate. (3) The inhibitors in doxycycline hyclate prevent elastase from functioning properly, thus elastin degradation is dramatically reduced and the development of wrinkles is delayed. Ultimately, there are many solutions to reduce the effects of elastase, however, the complete resolution of our degrading elastin is difficult to

    The identification of the melting point of the organic acid was done to find another characteristic of the acid and to test the purity of the recrystallized pure acid. A 2-4 mm layer of unknown sample was placed into a capillary tube sealed on one end. Then the capillary tube was inserted into the side a Bibby Sterlin device. The plateau was set to 200°C on the melting point apparatus. Once the plateau temperature was reached, the sample was watched carefully. When the sample first began to melt and when it was fully melted was recorded. These numbers were the range of the melting point. A slow melting point of the unknown organic acid and a standard sample was completed next. A new plateau was set about 10°C lower than the observed melting point of the unknown sample. This time once the plateau was reached, the heating was no more than 1°C per minute. This gave a much more accurate read of both melting points. If the standard did not melt in the range listed on the label of the bottle, that meant the machine was not working properly. The standard sample and the unknown organic acid melted in their appropriate ranges.…

    Purpose: Cells produce toxic wastes, in this experiment hydrogen peroxide, and without some sort of molecule to break it down the cell will die, along with the organism itself. However with the aid of an enzyme, catalase, hydrogen peroxide is able to be broken down into an intermediate and thereafter harmless substances water and oxygen. The goal of this lab is to measure the reaction rate of this process in different substances such as a liver, a vegetable, and breast tissue. By using variables such a pH and temperature we are able to how the rate of reaction is altered or improved. If it has improved, the optimum has been discovered and the enzyme will create a higher reaction rate. If above the optimal points, proteins will denature and the reaction rate will remain the same. This is vital for cellular activity for if homeostasis is not reached enzymatic activity will decrease or the enzymes will simply denature and the toxicity within the cell will increase killing the cell.…

    Introduction: The biological membranes are composed of phospholipid bilayers, each phospholipid with hydrophilic heads and hydrophobic tails, and proteins. This arrangement of the proteins and lipids produces a selectively permeable membrane. Many kinds of molecules surround or are contained within cells, but water is perhaps the single most important molecule in any living system (Hayden and McNeil 2012). Since water molecules are so small, they are constantly going into and out of the cell. Osmosis is a situation where more water molecules are moving across the membrane in one direction than the other (Hayden and McNeil 2012). During osmosis the net movement of water molecules will be from a solution that has a lower osmotic concentration to a solution that has a higher osmotic concentration. When a solution has a higher concentration of solute within the cell than out, it is called hypertonic. When a solution has a lower concentration of solute within the cell than out, it is called hypotonic. And when there are equal concentrations inside and out of the cell, it is called isotonic. The relative osmotic concentration can be determined by a change in mass of the tissue.…

    The homogenates provided were made by homogenizing tissues in a sucrose phosphate buffer in a 1:20 ratio. The protein concentration in bovine cells was measured by diluting the homogenate with a 1:5 ratio; 50 microliters of homogenate and 200 microliters of water. Then 5 known protein concentration samples which were 0.4, 0.8, 1.2, 1.6, 2.0 mg/ml of bovine serum were used to determine absorbance with a spectrophotometer. Two additional samples were made; one was blank and the other was for the specific homogenate sample. Then 3 microliters of bradford assay reagent, which indicates the amount of protein present by color, was added to all samples. The spectrophotometer was zeroed at 595 nm. A standard curve was made with the different absorbencies and concentrations. After the linear equation was formed, the unknown sample concentration was determined using the standard curve equation. A Gel Electrophoresis was used to perform a qualitative analysis. The use of 5 microliters of the homogenate was heated to 80 degrees Celsius. Then the homogenate was transferred to a 2-microliter-protein gel sample buffer. Samples loaded on to the gel was run at 100 v and stained with comassie blue; observations were made next lab.
