What are trans fatty acids‚ and where do they come from? We’re used to hearing about saturated and unsaturated fatty acids. Saturated fatty acids - which come from animal fats (meat‚ lard‚ dairy products) as well as tropical oils such as coconut and palm oils - raise the levels of LDL cholesterol. Unsaturated fats - which come from vegetable oils - in general‚ do not increase cholesterol levels‚ and may reduce them. Because saturated fatty acids were found to be bad for you a couple decades ago

Essential Fatty Acids (EFAs) are fats that are required by the human body‚ but cannot be made by the body; therefore they must be obtained from external forces such as food. EFAs are the building blocks of all fats and oils and are required for both metabolic processes and for fuel. EFAs form the main component in the fats carried in our blood stream (triglycerides)‚ fats stored in our bodies and of cell membranes (phospholipids). (Erasmus‚ 1993)‚ (Wikipedia‚ Essential Fatty Acids‚ 2012) Two fundamental

Introduction The purpose of this lab is to synthesize Lidocaine from 2‚6-dimethylaniline‚ using diethyl amine‚ 2-chloroacetyl chloride‚ acetic acid‚ and toluene. The Lidocaine was made by adding 2‚6-dimethylaniline to 2-chloroacetyl chloride in acetic acid. Sodium acetate is added in order to make the compound soluble. The product is dried‚ then treated with diethyl amine and toluene. This is refluxed using a water-cooled reflux condenser. The vapor is condensed by the cold water as the compound
