What is Organic? The word ’Organic’ means ’living’‚ and in practical terms‚ this means natural food that is grown and processed without chemical fertilizers‚ pesticides‚ herbicides or fungicides. Nothing unnatural is allowed so there are no growth hormones‚ antibiotics‚ preservatives‚ dyes‚ chemical coatings or irradiation allowed. There is no genetic engineering allowed in organic foods. Organic food is nothing else but good pure nutritional food - the way it used to be. Toxic overload

EXPERIMENT 5- A FISCHER ESTERIFICATION SYNTHESIS OF PEAR OIL One of the major uses of Esterification (C(=O)-C-R) is forming compounds with different odors which can be used to make different synthetic and natural flavorings. Using the chemical and physical properties of organic compounds‚ an ester was catalyzed from the reaction of a carboxylic acid with an alcohol‚ producing an odor similar to that of pear oil. The mechanism of this Fischer- Esterification process is outlined as follows:

mesmerized with the field of chemistry. The idea that I could start with one molecule and change it into a completely different compound both fascinated and thrilled me. I was at a predicament‚ on one hand I wanted to study medicine to help people‚ but I was far more interested in and passionate about the chemical processes and reactions. This changed when I took my first organic chemistry class. I want to make a career by applying chemistry to medicine and biology‚ especially in the realm of synthesizing

A carbohydrate is an organic compound that consists only of carbon‚ hydrogen‚ and oxygen‚ usually with a hydrogen:oxygen atom ratio of 2:1 (as in water); in other words‚ with the empirical formula Cm(H2O)n. The carbohydrates (saccharides) are divided into four chemical groupings: monosaccharides‚ disaccharides‚ oligosaccharides‚ and polysaccharides. In general‚ the monosaccharides and disaccharides‚ which are smaller (lower molecular weight) carbohydrates‚ are commonly referred to as sugars.

Woodlice Investigation Introduction: The ecological niche of the woodlice Porcellio scaber. The woodlouse Porcellio scaber is native to Europe but also commonly found in New Zealand. They live in cool‚ dark‚ damp microhabitats such as in rotting wood‚ under rocks‚ in caves and leaf litter. Small insectivorous rodents and birds as well as some spiders feed on woodlice. In the rotting log from which I gathered my specimens there were also millipedes‚ crickets‚ weta and spiders living. Woodlice

THE CHEMISTRY OF ORGANIC MOLECULES I. MACROMOLECULES-large molecules that are composed of smaller molecules and atoms that are bonded together. These are among the largest of all chemical molecules. A. Polymers-the largest of the macromolecules. These are composed of numerous‚ small identical subunits known as Monomers. There are 4 major polymers that are important for living organisms. These polymers are; carbohydrates‚ lipids‚ proteins and nucleic acids. B. Polymers
