among the amino acids. Enzymes usually work to complete one specific job which makes them specific catalysts. They also won’t be found all over the body‚ enzymes are found in neural cells‚ intestinal cells‚ and saliva. Enzymes are among the many organic macromolecules‚ they specifically belong to the proteins. Proteins are made of amino acids which link together to be folded into a three-dimensional figure. Enzymes are a different type of proteins because they make chemical reactions happen faster

When it comes to organic chemistry and the synthesis of specific products there is an abundant amount of routes that can be taken and still get you the same result. For the following experiment‚ the main focus is the use of a cycloaddition reaction‚ also known as Diels-Alder. According to the lab manual‚ this reaction consists of the addition of a diene and a dienophile and that the Diels-Alder reaction builds stereospecific ring compounds with ease (Weldegirma 80). The reaction takes place between
