The essential amino acid phenylalanine‚ with the molecular formula C9H11NO2‚ is abbreviated in the 3 letter form as Phe‚ or the single letter F‚ and is classified as a nonpolar amino acid due to the hydrophobic nature of the benzyl side chain (UPAC-IUBMB Joint Commission on Biochemical Nomenclature‚ 1983). The presence of the benzene ring determines that phenylalanine is an aromatic amino acid. Phenylalanine‚ being an essential amino acid‚ is needed by the body for many necessary biological functions

SYNTHESIS OF ESTERS USING GREEN AND NON-GREEN CHEMISTRY Abstract Esters are a class of organic compounds with the general formula RCOOR’. Ester also contributes the flavor and aromas in fruits and flowers. The esterification reactions will use in the procedure‚ which are the interaction of a carboxylic acid with an alcohol‚ aided by an inorganic acid catalyst (H2SO4). Moreover‚ the green method will not use any catalyst but using heating source instead (microwave). Based on the comparison of

CHAPTER SEVEN Discussion Questions 1. What role does forecasting play in the supply chain of a build-to-order manufacturer such as Dell? Although Dell builds to order‚ they obtain PC components in anticipation of customer orders and therefore they rely on forecasting. This forecast is used to predict future demand‚ which determines the quantity of each component needed to assemble a PC and the plant capacity required to perform the assembly. 2. How could Dell use collaborative forecasting

Synthesis of Methyl Stearate The purpose of this lab was the convert liquid methyl oleate to solid methyl stearate by catalytic hydrogenation. Firstly‚ we produced hydrogen gas using solid mossy zinc and sulfuric acid. Using the hydrogen produced in the previous reaction‚ we were able to convert the liquid methyl oleate to solid crystals of methyl stearate. A mineral oil was also used to bubbler was used to maintain the hydrogen pressure slightly above the atmospheric pressure and to prevent back-diffusion

MECHANISM: When the carboxylic acid is treated along with the acid catalyst and alcohol[R-OH]‚ It gives rise to the formation of ester along with water. Furthermore alcohol is used in an excess amount
