Mrs. Feeney Biology 9 October 16‚ 2012 Identifying Organic Compounds Objective: To use indicators to test for the presence of organic compounds in certain substances. Theory: Major types of organic compounds in some common foods are Lipids‚ Carbohydrates‚ and Proteins. An indicator is a chemical compound that changes color and structure when exposed to certain conditions and is therefore useful for chemical tests. The purpose of using distilled water as one of the substances in the test

objective of this experiment was to carry an organic synthesis; the preparation of salicylic acid from methyl salicylate. To do an organic synthesis‚ it is needed to chemically modify the molecules of another compound to end up with the desire compound. Methyl salicylate is the major constituent of wintergreen oil‚ which is why it was used in this experiment as the starting material. The new technique used in this experiment is heating under reflux. Many organic compounds‚ when heated become volatile and

Date: May 22‚ 2012 Name: Cristhian Valor Organic Laboratory Pre-Lab 1. Main reaction sequence including side reaction products: 2. 3 Sentence Summary of the Experiment: The OH group on the benzene ring in salicyclic acid reacts with acetic anhydride to form an ester functional group. Thus the formation of acetylsalicyclic acid (aspirin) is referred to as an esterification reaction‚ which requires the presence of H+ (H2SO4 in our case). The technique used to purify the aspirin content

BACKROUND INFORMATION Organic chemistry is the study of hydrocarbons and their various deviations. (Ex. natural gas‚ paper‚ proteins‚ carbohydrates) Saturated hydrocarbons are hydrocarbons with carbon-carbon single bonds. (Ex. C-C) Unsaturated hydrocarbons are hydrocarbons with one of more multiple carbon-carbon bonds. (Ex. C=C double bond‚ triple bond‚ or both) Stereoisomers have the same molecular and structural formulas but different orientations of atoms in space. Constitutional isomers

Proteins are arguably the most important things that people know the least about. As OpenStax CNX puts it‚ “Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules”. Proteins are “Macromolecules that contain nitrogen as well as carbon‚ hydrogen‚ and oxygen”(Miller‚ Kenneth R.‚ and Joseph S. Levine 48). Macromolecules are exceedingly large molecules that can be made up of several lesser molecules called proteins.

Plants are necessary in everything we do. Be it for eating‚ medicine‚ or even ornamental purposes‚ we still need plants. Fertilizers are like the vitamins for plants – they are not required yet the simple use of them can boost the quality of crops by folds. Fertilizers range from company manufactured items to compost heaps‚ which means they are the organic leftovers used again for the benefit of the nutrient cycle. Coffee is the awakener of the human race. Known to have

I enjoy a cup of organic fair trade coffee in the mornings. I have done this for a few months now. After I drink a big glass of water‚ I follow-up with the best organic coffee. For now‚ it has replaced my morning cup of green tea. Studies on caffeine continue and as each one comes to light‚ drinking coffee is no longer the dreaded bearer of health problems. For years‚ I didn’t drink coffee I avoided the caffeine. Because I like to keep my body clean and mean and I was under the impression the

Who Took Jerell’s iPod? Lab Purpose: Standardized Tests The purpose of testing the organic nutrients (vegetable oil‚ glucose‚ starch‚ powdered egg white) with each of the different indicators (brown paper towel‚ benedicts‚ iodine‚ biurets) was to determine the color it would turn with positive traces of the nutrient. The purpose of testing just the Distilled H2O was to determine the color it would turn with negative traces. Nutrient in the Different Foods The purpose of testing each of the
