Abstract Our study is entitled “The Feasibility of Aspartic Acid found in Oyster Shells as an additive ingredient in improving the absorbency of commercialized sanitary napkins.” The objective of the study was to extract a protein from the oyster shells to produce aspartic acid which can replace the manufactured polymer found in commercialized sanitary napkins. The significance of our study is that the product is an alternative in producing polymers. It is also environmental friendly; biodegradable

Acetylsalicylic Acid/Aspirin and N-(4-hydroxyphenyl) Ethanimidate/Acetaminophen respectively from Excedrin. The first reaction scheme to undergo acid-base organic extraction was to isolate the most acidic compound in Excedrin with a weak base‚ K2HPO4. We isolated the aspirin using aqueous base extraction‚ with Dipotassium phosphate then treated with HCl to force acidification. The mechanism for Scheme 1 is shown below: The second reaction scheme we used was also an organic acid-base extraction

ChE 171 Assignment 1. Essential and Non-essential Amino acids Amino acids are organic compounds which contain both an amino group and a carboxyl group and may be divided into two groups basing on whether they are produced internally by the human body or not: essential and non-essential amino acids (hyperphysics.phy-astr.gsu.edu‚ 2012). An essential amino acid (indispensable amino acid) is an amino acid which an organism needs to ingest because it is necessary for

not only the crops of the world but the health of the world’s inhabitants. Pollution affects the world’s water supply consequently creating what is known as acid rain. The Earth’s crop supply is nourished‚ damaged would be the better word‚ by the water affected by the pollution created in big cities as well as small towns. “The effect of acid rain on plants is grave. It not only damages the root‚ but also stops its growth and brings an end to the life of a plant (Megha Tiwari)” a science blogger concludes

Fatty acids and glycerol are the sub unit of most lipids. In the synthesis of a fat or oil three fatty acid molecules combine with one molecule of glycerol to form a triglyceride. Triglycerides make up about 95% of all dietary fats. This is formed by condensation (water is lost). Triglycerides are the chemical form in which most fat exists in food as well as in the body. They’re also present in blood plasma and‚ in association with cholesterol‚ form the plasma lipids. Fig 1.0 shows

Topic 11 - Yassine Assim Question: Explain the concept of a conjugate acid-base pair. Using equilibrium law and K‚ explain the relationship between the strength of an acid/base and its conjugate. Conjugate Acid-Base Pair: Conjugate acids and bases were presented by Bronsted-Lowry‚ who was a chemist who proposed the theory that both acids and bases required the transfer of a proton in order for there to be a reaction. An acid will donate a proton (proton donor)‚ forming what is considered to be a
