  • Uridine Synthesis

    This experiment monitored the synthesis of uridine from the deamination of cytidine through separating the contents of the reaction mixture using HPLC (High-performance liquid chromatography) at various time intervals since the start of the reaction. Cytidine and uridine standards are ran and the output of the HPLC will show two peaks based on the retention times of each compound. Identified the peak with the retention time of 2.422 minutes is cytidine and uridine has a retention time of 2.716…

  • Homeostasis Lab Report

    Introduction Homeostasis is the state of a stable internal cell environment. If the cell is not in a state of homeostasis, then the cell will not be able to live and function properly. The plasma membrane is selectively permeable and controls what molecules enter and exit the cell. The plasma membrane keeps the environment inside the cell relatively stable which is the state of homeostasis. The goal of this investigation is to see if the size of the cell is affected when the cells are put in…

  • Bromine Research Paper

    Bromine was discovered in 1826 by a French chemist by the name of Antoine-Jérôme Balard. It contains a molar mass of 79.904 grams per mole (g/mol). Bromine falls within group 7 of the periodic table and is a halogen. Its atomic number is 35 and is one of seven diatomic elements. Bromine is one of two elements that holds the natural state of liquid. I chose bromine for my independent paper because of many other elements I knew little to none about, I have never heard of bromine and was…

  • Tyrosinase Lab Report

    A chemical reaction’s rate is described by the amount of product formed. Substances that increase that rate are called catalysts. Catalysts are often proteins called enzymes. Enzymes change the pathway of the reaction between the products and the product. However, enzymes don’t alter the starting or ending points. Enzymes are effective by reducing the activation energy. The enzyme tyrosinase is located in melanocytes. These are cells that produce the pigment melanin. Melanin gives skin, eyes,…

  • The Reactions Of Halocoalkane's Reaction With Halogenalkane

    In experiment 2, we observed that the reaction of halogenoalkanes with aqueous alkali and water which contains dissolved silver nitrate. Halogenoalkanes are alkanes which have one or more hydrogen atoms replaced by halogen atoms such as fluorine (F), chlorine (Cl), bromine (Br) and iodine (I) which are the elements in group 7 in periodic table. Halogenoalkanes have the general formula, RX, whereby R is an alkyl or substituted alkyl group and X is any of the halogen atom. Besides, halogenoalkanes…

  • Enzyme Peroxidase Essay

    of photorespiration, photosynthesis or cellular respiration. This is significant because an enzyme operating in nonoptimal pH could have negative effects on the cell, and could pose a health threat to the organism. Enzymes proteins that speed up chemical reactions by lowering the activation energy. They do this by acting as a template for substrate orientation, stressing the substrates and stabilizing the transition state, providing a favorable microenvironment, or participating directly in…

  • Hydrogen Peroxide Reaction Lab Report

    Trend The constant, 0 v/v % hydrogen peroxide solution, did not react with the catalase, therefore it was recorded as 300+ seconds and had a reaction rate of 0 seconds-1. The 0.1 v/v % hydrogen peroxide concentration recorded a reaction rate of 0.17 seconds-1. The 0.2 v/v % hydrogen peroxide concentration, recorded a lower reaction rate than the 0.1 v/v% at 0.14 seconds-1. The 1 v/v % hydrogen peroxide concentration recorded higher at 0.49 seconds-1. The 3 v/v % hydrogen peroxide concentration…

  • Chemistry Chapter 11 Summary

    Chapter 11, “The Chemical Elements”, was of great interest to me. “Chemistry is the study is the study of the composition and structure of matter (anything that has mass) and the chemical reactions by which substances are changed into other substances (James T. Shipman 285).” In this summary paper, I will discuss some of the highlights of the chapter. The way I see it, God is the original/first chemist. He took His own creations (the elements in our Periodic Table) to make provisions for…

  • Pseudo-First-Order Kinetics Lab Report

    By using the pseudo first-order kinetics method, you are able to determine the rate law for the reaction between crystal violet and hydroxide ion. crystal violet hydroxide CV+ + OH- ————> CVOH Rate=k[CV+]m [OH-]n The objective for this experiment was to analyze the absorbance of the dyed molecule crystal violet using a colorimeter and the molar absorbance of the reactant. This data was used to calculate the concentration of…

  • Limiting Reactant Lab Report

    objective of this experiment is to get a better understanding of limiting reactants and chemical reactions as whole. It also helped us determine how the amounts of sodium carbonate and calcium chloride affect the chemical reaction made: calcium carbonate. Introduction: This lab was to show the relationship between reactants and products. In this case, we used calcium chloride and sodium carbonate. This made a chemical reaction and eventually formed calcium carbonate. The goal of this lab…
