Lab Report Macrocyclic Synthesis (Heme Analog) I. Purpose of Experiment and Introduction The purpose of this lab experiment is to prepare meso-tetraphenylporphin (TPP) and its copper‚ cobalt or zinc complex by condensing benzaldehyde with pyrrole in boiling propanoic acid. II. Introduction and Background There are two types of proteins that function as oxygen carriers: myoglobin (stores the oxygen) and hemoglobin (present in red blood cells and is responsible for oxygen transport)

It is an over-the-counter drug that relieves pain and reduced fevers. Acetaminophen is considered an alternate to aspirin since it does not irritate the stomach (Richman‚ 2004). It also has very

Lab Report Synthesis and Characterization of Aspirin (Acetylsalicylic Acid) The Synthesis and Characterization of Aspirin (Acetylsalicylic Acid). Summary: In this experiment‚ we produced 4.21 g of acetylsalicylic acid. Our theoretical yield was calculated to be 5.22 g. Therefore our % yield was determined to be 80.6%. The experimental boiling point range of acetylsalicylic acid was found to be 130-132° C. The true melting point of acetylsalicylic acid is 135° C‚ therefore our percent

agent for rabies. The rabies virus is enveloped‚ it is covered/surrounded by a covering for protection. The rhabdovirus contains up of a helical ribonucleoprotein core(RNP)‚ and an envelope that is surrounding the viru (CDC‚2011). Eukaryotes have a synthesis process between protein and RNA that forms the ribonucleoprotein. The rabies genome has five protein components: nucleoprotein‚ phosphoprotein‚ matrix protein‚ glycoprotein‚ and polymerase protein(CDC‚2011).

Name Period Date The Synthesis of Aspirin Background Pharmaceutical research labs perform chemical reactions between organic molecules that contain mostly carbon. Since the atoms in organic molecules tend to be nonmetals‚ then the bonds that hold them together are covalent bonds. Only a few elements on the periodic table are nonmetals: C‚ N‚ O‚ S‚ Cl‚ and F. This small number of elements can be bonded together in different quantities‚ bonding types (single‚ double‚ triple bonds)‚ and structural

Synthesis Argument Do you want to have everything decided for you? Does that make you feel safe and comfortable? How about confused and concerned? Do you see too many laws that restrict your freedom? Government protects people from threats and is not to unnecessarily legislate that restricts freedom and governs morality but to leave that to the realm of individual responsibility. Government is defined by the Webster Dictionary as "the system by which a state or community is governed." In America

Alum Synthesis: The Chemical Process of Recycling Aluminum Introduction By recycling aluminum cans‚ the costs and energy savings are dramatically more resourceful and efficient than producing aluminum from what it is naturally found in‚ bauxite ore. The process of recycling aluminum to produce potassium aluminum sulfate‚ a common alum‚ will be done through a serious of chemical reactions. Through this reaction‚ percent yield will be determined.

CHEMISTRY 101.1 Intermediate Chemistry Laboratory I Institute of Chemistry University of the Philippines‚ Diliman I. Synthesis of Salicylic Acid Purpose: Part I of the experiment illustrates the base hydrolysis of an ester‚ methyl salicylate‚ to form salicylic acid through nucleophilic acyl substitution. Procedure: Dissolve 12 g NaOH in 70 mL water in a 150 mL round bottom flask. Add 5.0 mL methyl salicylate and reflux the reaction mixture at its boiling point for 15 minutes using a stirrer

In modern day‚ man does not truly think about how much the earth means to life. On the contrary‚ humans aspire to cease Mother Nature’s beauty with the replacement of modern day cities made up of synthetic nature. Since the dawn of the twentieth century‚ a major theme in the American Arts has been the protest against man’s destruction of the natural world. With this in mind‚ as very well argued in Chief Seattle’s article “Respect”‚ humans fail to be conscious of the physical and sentimental value

aqueous solution of formaldehyde is called formalin. The commercially available formalin has 10 to 12% methanol with a few impurities like aluminum and copper. Almost 21 million tonnes of formaldehyde is produced annually all around the world. Synthesis of Formaldehyde Formaldehyde is produced by catalytic oxidation of methanol. A mixture of molybdenum and iron or silver is used as a catalyst in such a reaction. But a more commonly used process is FORMAX. In this process‚ methanol and oxygen
