lipids. Various experiments are done on lipids. Some tests are for saturation‚ presence of certain compounds‚ or for the different chemical reactions that lipids undergo. Lipids may be composed of esters‚ amides‚ alcohols‚ cyclic‚ acyclic‚ or polycyclic structures‚ and may also be a combination of these. OBJECTIVES General Objective: At the end of the experiment‚ students must be able to familiarize themselves with the different classes of lipids and to be able to identify each kind of lipid

side effects of them on our daily diet. Both BHA (Butylated hydroxyanisole) and BHT (Butylated hydroxytoluene) are phenolic compounds. The phenolic compound is a type of organic chemistry which made of a hydroxyl group (-OH) and bonded to an aromatic hydrocarbon group known as phenols or phenolics (James‚ 2012). BHA and BHT are developed since 1947‚ which were used to check the oxidation in rubber products‚ before they were used as food preservatives. Nowadays BHA and BHT are widely used in food products
