Angiotensin-converting enzyme

Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism. Some enzymes help break large molecules into smaller pieces that are more easily absorbed by the body. Other enzymes help bind two molecules together to produce a new molecule. Enzymes are highly selective…

the enzyme concentration versus the reaction time of an enzymatic reaction, and the effects of the reactants and products concentration direction of the reaction. Specifically, in this lab the enzymes salivary amylase and phosphorylase were looked at the effect of the enzyme concentration versus the reaction time of an enzymatic reaction were observed by the iodine test along with the benedict’s test. Enzymes are known as biological molecules which catalyze different reactions and all enzymes…

There are four types of interactions that stabilize a protein and give it structure at the tertiary level. Hydrophobic interactions are nonpolar molecules, they generally have a long chain of carbons that do not interact with water molecules. RGroups prefer to interact with each other internally and away from water (Wolfe, G. (2000). Thinkwell biochemistry - 2.7.4 Tertiary Structure). This interaction contributes significantly to the folding and shaping of a protein. Hydrophobic interactions…

Introduction Background: Atropine as an Alkaloid compound has been in use for ages since the times of the Roman Empire as it was used for local anesthesia. The compound was derived from common organic compounds like Tropane alkaloid that is synthesized by most solanacea family and also from berries of the plant Atropa belladonna. Comprehensive research on the compound Atropine was first carried out by German chemist Friedlueb Ferdinad Runge between 1795-1867, later German based pharmacist…

On Thursday, October 27 we did experiment 11 call separation of casein from milk. The purpose of this experiment to learn to separate purify a substance from a biological fluid; separate casein from milk in this experiment. As well as learning to write a formal lab report. In the beginning of this experiment, we set up the water bath to heat the milk. I fill 1/3 of a 400 mL beaker with water. I weigh an125 mL Erlenmeyer flask and find it weighs 69.70g.Then I add 70 mL milk and put the flask…

(ACS, 2016). What is a specific example that exists for pharmaceutical reactions? A specific example that exist for a pharmaceutical reaction may consist of a transfer of an acetyl group from an aspirin molecule to a serine amino acid of a protein enzyme known as a COX inhibitor. An example of a balanced chemical equation would be aspirin+COX→salicylic acid+COX-OAc (Ilocis, 2016). What is the difference between diagnostic chemical reactions in healthcare? A diagnostic chemical reaction…

The hypothesis that rate of respiration of chickpeas is highest at room temperature is not supported by the data, although there was error in the data. The data from the lab showed rate of oxygen consumed to be the highest at 1.5 degrees Celsius with a rate of .0124ppt/min/g. At room temperature there was a rate of .0077ppt/min/g, and at the hottest temperature (95.6 degrees Celsius) a rate of -.0131ppt/min/g, meaning that oxygen was not consumed but actually increased in concentration in the…

The data in Figure 1 supported both our hypothesis and our predictions. The solute concentrations affected our model organism the Gallus gallus domesticus. The weight of the G. gallus domesticus egg has a greater decrease in mass when added to a higher concentrated solution than a lower concentrated solution. The data also supported the prediction that the mass of the G. gallus domesticus egg in 10% NaCl will weigh less than the G. gallus domesticus egg in the 1% solution. Diffusion and osmosis…

Enzymes are protein molecules that occur in all living things on earth and enable chemical reactions. Enzymes not only provide an alternate pathway for a chemical reaction, with a lower activation energy, they also bring substrates together in an optimal orientation, thereby speeding up the rate of reaction (Slide Share 2016). In an enzyme catalyzed reaction, the substrate (reactant) binds to the active site and forms and intermediate substance known as the enzyme-substrate complex with the…

begins. However, since his data shows him becoming dehydrated immediately after exercise (dark yellow urine), he may want to take frequent water breaks during his exercise routine so that his body can remain constantly hydrated and healthy. 8. Angiotensin II has the kidneys boost extracellular fluid which causes blood pressure to rise in two ways. It can cause the posterior pituitary to release its’ storage of antidiuretic hormone which causes water reabsorption in the kidneys. Second, it…
