CHEMISTRY OF LAETRILE ( AMYGDALIN / VITAMIN B17) AUTHORS: Audrey De Jesus Rowie Joy Pilapil Shariel Eunice Juanillas Polytechnic University of the Philippines College of Science Department of Nutrition and Dietetics Sta. Mesa‚ Manila ABSTRACT Vitamin B-17‚ commonly known as "Amygdalin”‚ is a plant substance found naturally in raw nuts and the pips of many fruits‚ particularly apricot pips‚ or kernels. It is also present in plants such as lima beans‚ clover and sorghum. Laetrile‚ on the other

Chemistry of love: how science can explain our daily lives? By Barton Dong Loving and being loved adds richness to our lives. When people feel close to others they are happier and even healthier. Love helps us feel important‚ understood‚ and secure. When people think of love‚ a romantic emotional scene appears in their minds. In the heavy days of a mutual crush‚ pulses race‚ knees go weak‚ and heads reel. So strong are these feelings‚ they’ve launched a thousand songs and

reactants used and the amounts of products formed in a chemical reaction”. Basically‚ Stoichiometry is the science of counting and studying the relationship between the amounts of the reactants to the product. To think of stoichiometry outside of chemistry‚ imagine a bookshelf. To assemble the bookshelf you may need 3 planks of wood‚ 1 giant plank of wood‚ and 20 nails. Even though the amount of the reactants is high‚ the product would be only one bookshelf. Stoichiometry is basically studying the

August 22‚ 2013 Assignment 1: The Chemistry of Life Effects of Acid Rain There are many different types of negative effects acid rain has on the world. Acid rain is the mixture of wet and dry deposition from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. Pollution contributes to the forming of acid rain. One of the main causes is industrial burning of coal and other fossil fuels the oxides they contain and combine with atmospheric water which forms acids.

CONCEPTS IN ORGANIC CHEMISTRY • Inductive Effect : Inductive effect is defined as permanent displacement of shared electron pair in a carbon chain towards more electronegative atom or group. Types of Inductive effect : 1.Negative Inductive Effect : (—I effect‚ Electron withdrawing effect) when an electronegative atom or group (more electro negative than hydrogen)is attached to the terminal of the carbon chain in a compound‚ the electrons are displaced in the direction of the attached
