with an alkyl group‚ it becomes an ester group. “The reaction typically gives 60-70% of the maximum yield” (Staudt‚ 80). The reaction of an ester could also be reversible to make carboxylic acid and alcohol; this process is called hydrolysis. But when‚ “the base-promoted decomposition of esters yield an alcohol and a salt of the carboxylic acids; this process is called saponification”; In other words‚ it is the process of making soap (Staudt 80). Moreover‚ Esters are liquid at room temperature no

Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and

Experiment 2: Starch Hydrolysis by Amylase Theoretical Background Polymers of carbohydrates are called polysaccharides‚ and make up some of the most important naturally occurring compounds [1]. They have thousands of monosaccharide units linked to each other by oxygen bridges. They include starch‚ glycogen‚ and cellulose‚ all three of which yield only glucose when completely hydrolyzed [2].
