Identifying Biological Molecules with Colorimetric Chemical Tests

Identifying inorganic compounds using qualitative analyses and chemical tests Jessica Vithayathil U84363206 CHM 2045L Section: 033 Aaron Clark October 13, 2016 Introduction Due to climate change during the turn of the 21st century and overall population growth, scientists have noticed greater amounts of negative impact on water sources (Barber, 2011). Waste Water Treatment Plants (WWTPs) have been identified as one of the root causes of stress for these water sources (Barber).…

confirmation) could be isomerized to dimethyl fumarate (trans confirmation) by heat, light, or bromine. In order to investigate chemical properties of when the molecule is in a chiral vs. achiral environment, enantiomers of carvones were compared. Enantiomers and diastereomers are the two classes of stereoisomers. Stereoisomers are molecules that have the same chemical formula, but differ in their three-dimensional arrangement in space. Enantiomers are mirror images of each other that are non-superimposable…

Chemical and Biological Weapons Chemical and biological weapons are the most dangerous threats that our soldiers face today. But just how much do most of us know about them? The American public had been bombarded by stories of how our government keeps secret weapons, does secret experiments, and the everlasting conspiracies. And many accept it all. Rather than simply trusting our government, (which is perhaps as foolish as believing several unsubstansiated theroies), I’ve compiled several simple…

Detection of Biological Molecules Introduction: Without carbon, nitrogen, hydrogen, sulfur, oxygen and phosphorus, life wouldn't exist. These are the most abundant elements in living organisms. These elements are held together by covalent bonds, ionic bonds, hydrogen bonds, and disulfide bonds. Covalent bonds are especially strong, thus, are present in monomers, the building blocks of life. These monomers combine to make polymers, which is a long chain of monomers strung together. Biological molecules…

As many scholars have suggested, Libya’s renouncement of nuclear, chemical and biological weapons shows us a possible solution for the so-called rogue regimes including North Korea. North Korea presumably continues to possessing nuclear, biological and chemical weapons programs and continues to develop its nuclear program to the extent that the Democratic People’s Republic of Korea (DPRK) conducted its fifth nuclear test. Experts warn that DPRK can reach its capacity to complete its Inter-Continental…

Spectrophotometrically Identifying Alfalfa Sprouts’ Chloroplasts and Lysosomes Isolated in a Sucrose Gradient Introduction: Conceptualizing an organism with a biological lens involves understanding the organism’s components and how their individual functions characterize the overarching entity. For a body, this means understanding organs and tissues. For a cell, this means classifying its organelles and discerning their functions. Analysis of subcellular components has become a major focus in biochemical…

Problem: There are thousands of chemical reactions that occur in an organism that make life possible. Most of these chemical reactions occur too slowly on their own. Enzymes are protein catalysts that speed up chemical reactions in a cell. Catalysts are not changed by the reactions they control, and are not used up during the reaction. Enzymes therefore, can be used over and over again. Enzymes are large complex proteins made by the cell and allow chemical reactions to take place at the temperature…

Biology 100 Lab Laboratory Report Title: Identifying the four major classes of macromolecules through various tests. Group Members: Antonia Johnson, Payton Ewing, Lenneisha Hepburn, Kendisha Hanna, Introduction: Macromolecules also known as biological molecules are monomers which are the simple units of polymers. All macromolecules contain carbon and hydrogen which are found in organic compounds. In this Experiment we will test for the presence of protein, starch, lipids, and sugars by analyzing…

thought it was very interesting, so I decided to do a report on it. If you keep reading, you'll find out what I've found out. Who funds the making of chemical or biological weapons? The answer is many people. However… the government is the main source of money. For example, they make labs built to find defenses against new chemical or biological weapons. The catch is that in order to find new defenses, they must first build new weapons. That brings us to terrorists. Government officials make…
