Angiotensin-converting enzyme

α-Lactalbumin, a multifunction protein in milk, forms an enzyme complex with galactosyltransferase that catalyzes the last reaction in lactose synthesis.1 α-Lactalbumin has one Ca2+ binding site and several Zn2+ binding sites as well as many intermediary folding states, making it ideal for research involving the effects of cation binding on protein interactions as well as research on protein misfolding.1 α-Lactalbumin gives milk an antimicrobial property, making it important for infant health,…

There are factors that can affect the enzymatic activity. Enzymes are known to speed up the biological reactions. It is specific to its substrate which in this experiment is known to be catechol. The catechol oxidase is used in all parts to express the concentration in the enzyme reacting into ortho-quinone (Schultz, 2006). The catechol oxidase if from the potato that was used in this experiment. The enzyme was extracted as the full strength after centrifugation and used the homogenization as…

Topic: Identifying Unknown Substances. Equipments: • 5 test tubes. • 1 beaker of Acid 1 beaker of water • 4-Litmus papers • 2 Pipette bulbs. • 1 robber stopper. • 1 Bunsen burner. • Q-tips(4). • Scoopula. Observation: Which substance is which? Hypothesis: All the unknown substances that we have are soluble in water. Procedure • We had a 4 test tubes filled with small amount of white powder. We labeled each test tube. For example the first test tube was labeled as “Substance A” , the second…

In this investigation, electrolyte content will be measured and compared to the sugar content to give a measurement of how drinks compare in terms of benefit during exercise. The independent variable will be the drink being tested, and the dependent variable will be the electrolyte and sugar content of that drink. Electrolytes are positively or negatively charged ions that are essential for survival. Positively charged electrolytes move towards a cathode, while negatively charged electrolytes…

pH will affect enzyme function by increasing the reaction rate because as temperature increase so is the rate of reaction and extremely high or low pH will result in the denatured by decreasing the reaction rate. The function of this experiment was to investigate the influence of the concentration of enzyme on the rate of reaction. The rate of reaction in this experiment was subjected by the amount of Guaiacol, H2O2, Extracts, and Buffer (pH5). The reaction rates with different enzyme…

〖Na〗^+and K^+channel relationship Figure one shows the temporal relationship between 〖Na〗^+ conductance (g_Na) and K^+ conductance (g_(K )), and the relative changes in the V_m during an action potential. 〖 g〗_Na increased as the V_m moved towards 0 mV causing depolarization of the membrane and started to decrease immediately after the peak of the action potential. Whereas, g_(K ) increased immediately following the action potential peak during the repolarization of the plasma membrane where…

Imagine trying to figure out one possible combination to a mixture, when there are over 100 possibilities. The 8th graders had to look at the physical and chemical properties, to somehow figure out the mixture. A group of students thinks that Baking Soda and Citric Acid is what’s in the mystery mixture. That group thinks that Baking Soda and Citric Acid is in it for a lot of reasons. One reason is that the mystery mixture has circular round objects in it and the Citric Acid is circular and…

various temperatures on Enzyme activity Introduction: The basic properties of life revolve around chemical reactions. Without the presence of enzymes some of life's processes would not happen easily. An enzyme is a macromolecule serving as a catalyst, they are generally a protein based molecule, as it is in the lab, Enzymes are organic catalysts that control the rate of chemical reactions in cells while not being permanently changed or without being consumed, which makes enzymes different…

Introduction Enzymes are an important biological catalyst that is absolutely crucial for life to exist. The ultimate purpose of this experiment was to examine enzymes and how they function in cells, explore the result that concentrations and environmental factors have over these functions, and lastly to read and interpret graphs related to enzyme function. This type of study had various parts, therefore there are various hypotheses. The first being, if it is potato extract, then it will contain…

Adenosine Triphosphate (ATP) is a nucleic acid present in organisms with the primary function of providing energy. It is comprised of three phosphate groups with one adenosine attached and releases energy by being hydrolysed into Adenosine Diphosphate (ADP), therefore one bond is broken and a phosphate molecule is lost. ATP can only be reproduced through phosphorylation which results in the addition of one phosphate to Adenosine Diphosphate. ATP must be regenerated in order to allow an organism…
