The halogen-containing organic compound I decided to research is chloroform. Chloroform is also called trichloromethane, its molecular formula is CHCl3. It is, “a colorless liquid, half again as dense as water and of about the same viscosity, chloroform has a heavy, etherlike odor and a burning sweetness of taste, being about 40 times as sweet as cane sugar” (Chloroform, 2016). In addition, “it is an important solvent for gums, resins, fats, elements such as sulfur and iodine, and a wide variety

My science fair project is based on a chemical reaction taking place to turn a hot substance into ice. A chemical reaction is a reaction that changes the substances original identity to a different chemical identity. There are many different types chemical reactions in chemistry, but the one we are going to be focusing on are exothermic reactions. Exothermic reactions are reactions that transfer energy to the surroundings. The exothermic reaction is a reaction that gives off more energy than it

poisonous, however this is only specific to the violet-blue coloured flowering plants; the yellow flowered plants, most commonly known as eranthis are not poisonous. Aconitine, which is a highly poisonous alkaloid derived from the aconitum plants has a chemical formula of C34H47NO11. Aconitum napellus is found wild in some parts of England, mostly in the western counties and also in South Wales and it’s habitat is most commonly mountain slopes; therefore the plant can also be found in parts of the Himalayas

Enzyme inhibition refers to a decrease in enzyme-related processes, enzyme production, or enzyme activity. Various clinically critical communications between drugs result from CYP450 hindrance. CYP450 inhibitors are diverse in their selectivity toward proteins and are arranged by their systems of activity. A few medications are strong focused inhibitors and go after the dynamic site, yet they are not a substrate for the compound (e.g., quinidine and CYP2D6), while different medications are noncompetitive

In this experiment, a Diels-Alder cycloaddition reaction was performed. This reaction was performed with 1,3-cyclopentadiene and maleic anhydride. The 1,3-cyclopentadiene was obtained by cracking dicyclopentadiene. The Diels-Alder reaction resulted in 2.0881 grams of clear white crystals, which were confirmed to be cis-norbornene-5,6-endo-dicarboxylicacid anhydride. This amount determined a percent yield of 83.16 %. The percent yield is only 83.16 % because some product was lost during vacuum filtration

LAMP reaction The LAMP reaction was performed by using Loopamp DNA amplification kit, Eiken chemical CO., LTD., JAPAN. The 2X reaction mix composed of 40 mM Tris-HCl (pH 8.8), 20 mM MgSO4, 16 mM (NH4)2SO4, 0.2% Tween 20, 1.6 M Betaine and 2.8 mM dNTPs each. The LAMP reaction was optimized by incorporating different concentrations of primers and temperature. The LAMP reaction of total 25µl volume consisted of 2X reaction mixture (12.5µl), 2.0 μM FIP and BIP; 0.8 μM LF and LB; 0.2 μM F3 and B3 each

Ependymin, a secretory glycoprotein that relates to long-term memory, had only been found in vertebrate species. The protein was proposed to be vertebrate-specific molecules that explain the evolution of the chordate nervous system (Landers et al., 2001; Venter et al., 2001; Ponting and Russell, 2002). Yet the gene that relates Ependymin were found in sea cucumber Holothuria glaberrima in the experiment, which was not found from invertebrates before. Using cDNA synthesis and analysis by common

Introduction Tyrosinase is an enzyme that controls the production of melanin, which is a pigment found in plants, animals, bacteria and fungi. Both tyrosinase and melanin is found in nearly all cells. Melanin is especially important in determining the skin and hair color of mammalians. It is synthesized by an array of oxidative reactions of the amino acid tyrosine when tyrosinase is present (Kim, Y. & Uyama, H., 2005). Tyrosine is first hydroxylated into dihydroxyphenylalanine (DOPA), which is then

Hello, I’m oxygen particle but you can call me Oxy, and today I’ll be taking you on an exclusive tour through the human body where we will meet many of my important friends, in relation to the Respiratory System. To start off with today, we will enter the human body as air through my friend, Nostril. Nostril has an important job to do; it’s up to Nostril to give the tour groups of oxygen particles a warm welcome, by filtering and removing larger unwanted particles and moistening them with his tiny

The data I will collect, is the moles and grams for each unknown compound, calculate the g/mol for the unknown compounds, and calculate the molar mass for the known compounds. To identify the unknown compounds, we first weighed all seven of the unknown bags. To find the weight of the unknown compound in the bag, we first subtracted the weight of the bag by first weighing an empty bag and pressing the zero button to zero out the weight of each for the seven unknown compounds. The mol of each unknown
