BIOCATALYSIS IN ORGANIC SOLVENTS: FUNDAMENTALS ENZYMES IN ORGANIC SYNTHESIS 1. Enzymes catalyze a broad spectrum of reactions with high turnover numbers. Rate enhancements approach 1012 fold. 2. Enzymes may accept a wide range of substrates. 3. Enzymes are highly regio and stereoselective. 4. Enzyme reactions take place under mild conditions; this minimizes problems of isomerization and racemization. 5. Enzymatic processes are less hazardous and polluting than conventional chemistry-based methodologies

CHAPTER 5 The Time Value of Money CHAPTER ORIENTATION In this chapter the concept of a time value of money is introduced‚ that is‚ a dollar today is worth more than a dollar received a year from now. Thus if we are to logically compare projects and financial strategies‚ we must either move all dollar flows back to the present or out to some common future date. CHAPTER OUTLINE I. Compound interest results when the interest paid on the investment during the first period
