The Chemistry of Lipids Experiment #8 Objective To observe the solubility of lipids in polar and nonpolar solvents and to compare saturated and unsaturated fats in their chemical reaction with bromine. The percent fat in a food will be determined by extraction of the fat and weighing it. Introduction Lipids‚ by definition‚ are natural substances that do not mix with water but dissolve in organic solvents. There are several classes of lipids‚ including: fatty acids‚ waxes‚ triacylglycerols

effect of citric and buffered lactic acids on the flavour of hard-boiled sweets and the effect of acids on various flavours in high temperature applications. Introduction Materials and Methods An amount of water‚ sugar and glucose syrup of 30g‚ 100g and 70g were weighed respectively into a stainless steel pot. The mixture was then heated and removed immediately from the induction cooker after reaching the desired temperature of 145˚C. Flavours of 0.51g and acid of 1.20g was added immediately afterwards

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
