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

EMISSIONS FROM ADIPIC ACID AND NITRIC ACID PRODUCTION A C K N O WL E D G E M E N T S This paper was written by Heike Mainhardt (ICF Incorporated) and reviewed by Dina Kruger (USEPA). ABSTRACT Nitrous oxide (N2O) is generated as a by-product during the production of adipic acid and nitric acid. The main use for adipic acid is as a component of nylon-6/6; thus production trends are closely correlated with nylon consumption trends. Worldwide‚ there are very few adipic acid plants. The U.S. is

EXP-10 CHEM 233L SYNTHESIS OF p-BROMOANILINE Introduction: In this experiment‚ p-bromoaniline was synthesized in three steps starting from aniline. Since the amino group of aniline is a strong activator of aromatic ring‚ direct bromination is impractical (equation 1). In order to make a desired product‚ amino group needed to be protected as the acetamide which also maintained ortho and para position but slowed down the rate of reaction (equation 2). Slow reaction rate would increase

acetaminophen. p-aminophenol and acetic anhydride were used to create acetaminophen and acetic acid. The acetic acid mixed with acetaminophen created an impure sample‚ which was purified through the addition of a water/methanol solution. The percent recovery of acetaminophen from the impure sample to the pure sample was 76%. The melting point of the pure sample was 167C - 169C. Introduction: Formulation of acetaminophen involves treating an amine with an acid anhydride to give rise to an amide

Folic Acid is a B vitamin‚ specifically B9. It is an essential nutrient required by the body to create healthy new cells. While we hear about it mostly in regards to pregnancy‚ it is important to understand that the need for folic acid goes even beyond this. Folic acid is essential for the body to create red blood cells which in turn prevents anemia. It is also plays an important role in the metabolism of homocysteine‚ an amino acid. The recommended dietary allowance (RDA) for all men and women

Indicators can be used to determine whether these substances are acidic‚ basic or neutral. Manufactured indicators are one type and the second type is natural indicators. Believe it or not‚ the majority of fruits‚ vegetables and flowers contain pigments which may be used as acid-base indicators. For example‚ Red cabbage contains within
