he relationship between structure and function reaches its ultimate expression in the chemistry of amino acids, peptides, and protein Amino acids are carboxylic acids that contain an amine function. Under cer- tain conditions the amine group of one molecule and the carboxyl group of a second can react, uniting the two amino acids by an amide bond. Amide(peptide)bond

N ow that we're familiar with the structure and preparation of alkenes, let's look at their chemical reactions. The characteristic reaction of alkenes is addition to the double bond according to the general equation:

1 a) In an M&M frictionless environment, where there are no taxes and contracts are costless to make and enforce, the wealth of the shareholder is the same no matter what capital structure the firm adopts. In such an environment, neither the stock price nor shareholders' wealth would be affected
