AMINO ACIDS SUSMITA DAS SWAPNA MONDAL OBJECTIVES To study about Amino acids. To study the classifications of amino acids based on different headings. To study the functions of amino acids. INTRODUCTION Amino acids:• Amino acids are monomers of protein. • Amino acids are group of organic compounds which contain two functional groups. One is Amino group(NH2) and the other is Carboxyl group(COOH). • Proteins are broken down into amino acids on hydrolysis. • Each amino acid also have a

The Synthesis and Determination of Empirical Formula for Magnesium Oxide Aim: To determine the empirical formula for magnesium oxide. Data Collection: Table 1 Mass of empty crucible‚ crucible + Mg (roughly 1cm pieces of a 15-cm piece of magnesium ribbon)‚ and crucible +MgxOy. (mass measured with an analytical balance). The mass of crucible + MgxOy was obtained after a continuous process of heating‚ letting cool‚ heating with water enough to immerse the content and letting cool of the Mg. Mass

aerodynamic lift force and engine’s thrust so that the plane flew with constant velocity. 3. The spring was extended to 3cm under mass of 500g. Determine the spring constant. 4. The distance between two planets of masses 25x1025kg and 30x1025kg is 1012km. Calculate the attractive force between them. 5. The load with mass m=1.5kg is attached to the string of length l=1.5m and moves along a vertical circle with constant velocity v=1.5m/s. What are the maximum and minimum tensions in the string

Aspirin analysis Introduction Aspirin‚ which is also known as acetylsalicylic acid. C9H8O4 is the chemical format for Asprin. The chemical structure of aspirin: Aspirin is anti-inflammatory. Aspirin is prepared by chemical synthesis from salicylic acid‚ by acetylation with acetic anhydride. The fact that it is an acid allows us to quantify the amount of aspirin in a solution. We would do this by by using an acid-base titration. Sodium hydroxide (NaOH) will be used In this experiment as the

Determination of Chemical Formulae: The Reaction of Zinc and Iodine By Sarah Abstract: The main objective of this experiment was to use to the reaction between zinc and iodine to examine the validity of the Law of Conservation of Mass and the Law of Constant Composition. The Law of Constant Composition was tested by determining the mass of each of the reactants‚ zinc and iodine‚ and comparing their total to the mass of the zinc iodide product plus the excess zinc. The total mass of the reactants

Micah Garman - CPO# 248 Dr. Burke - Greek Exegesis II Exegetical Paper Sexual Purity: A Call to Holiness INTRODUCTION The world in which Christians live today is very similar to the world that Paul taught‚ lived‚ and traveled in. Christians are surrounded by and struggle with the issue of sexual purity that believers struggled with in Paul’s day. Sexual immorality is a result of a much larger problem: the refusal of God’s call to be holy. The pagan Gentiles during the New Testament had a

Safety Precautions for Synthesis of Acetic Anhydride Acetic Anhydride Acetic anhydride is an irritant and also flammable‚ therefore gloves and goggles should be worn at all times during the experiment. It is reactive to water‚ so in the case of fire‚ alcohol foam or carbon dioxide is preferred to use as an extinguisher. This chemical has harmful fumes and use of a fume hood is strongly recommended. Sulphuric and Salicylic Acid These acids may irritate the skin in high concentrations. Take

Nitric acid is a highly reactive oxidizing agent used in making fertilizers‚ explosives‚ and rocket fuels‚ and in a wide variety of industrial metallurgical processes. It is also a component of acid rain. Its chemical formula is HNO3 and it has been known as “aqua fortis”‚ which means strong water‚ to alchemists. It is a transparent‚ colorless to yellowish‚ fuming corrosive liquid. Nitric acid is a strong acid and therefore it completely dissociates in water. It has a gravity of 1.41 and the concentration

Sarah Khan Bivins-5th April 20th‚ 2013 Protein Synthesis Every day‚ you take in an abundance of different biomolecules; one of them being proteins. Have you ever wondered how proteins are made? They don’t just grow from a tree or fall from the sky‚ they are made through a process called protein synthesis. Protein synthesis is broken up in two two steps: transcription and translation. Transcription starts inside the nucleus when the DNA is unzipped by helicase. Following that‚ the mRNA nucleotides

percentage yield: Once the percentage yield is calculated then the quality of the apparatus and procedure can be determined to obtain better results and more product in the future. The purpose of this experiment‚ is essentially to determine the purity of the product that is collected and filtered and recrystallized. Experimental Procedure: The experimental procedure used for this experiment was outlined in the CHEM 123L lab manual‚ Experiment #1. All steps were followed without deviation. Experimental
