    Experiment #4 (10/31/14) Lab Review Objective To introduce the basic molecules of life and to test for their presence in different substances. Introduction Macromolecules are in all forms of life.  These organic compounds are carbohydrates‚ lipids‚ proteins‚ and nucleic acids.  These are monomers and they link together into long chains that form polymers.  Different reagents can be used to find the presence of these macromolecules. Proteins are made of carbon‚ hydrogen‚ oxygen‚ nitrogen‚ and sometimes

    Edward Dickson CHE101 DS-01 Experiment Date 7/21/2013 Report Submitted 7/21/2013 Title: Experiment #8: Ionic Reactions Purpose: In this lab we will work with aqueous solutions of ionic substances and determine if they are soluble. If the solution appears milky than it is known as a precipitate reaction‚ meaning it is soluble‚ and that the ions separated and became surrounded by water. Precipitates in this experiment are electrically uncharged. To identify which compounds are

    borneol than toxic isoborneol? An experiment of making borneol from camphor (FIGURE-3) is performed in two different methods‚ Sodium Borohydride Reduction and Meerwein-Ponndorf-Verley Reduction‚ to compare the relative product ratio of borneol to isoborneol. The concept of reduction and also oxidation‚ the opposite procedure of reduction‚ deals mostly with electron transfer between atoms. It will not be elaborated here‚ but the reduction procedure involved in this experiment is basically adding hydrogens

    preparing lots of different food at the same time. If you look at cooking websites they will suggest to use lemon water. In our experiment we will attempt to find out which is better at preserving the sliced‚ chopped‚ and or diced food. Since our experiments are limited by time and costs‚ we will stick to the simplest of the available options. So this study or experiment was already tried by the chefs and scientists at America’s test kitchen. At this link you will find the source of our idea for this
