Three samples of oils, namely safflower oil, peanut oil, sesame oil are mixed with one drop of iodine. The degree of unsaturation of animal fats with that of the oils tested should be determined. Concept Introduction: Fat consists of long chain fatty hydrocarbons that have carboxylic acid . These are further classified as unsaturated and saturated fats. Unsaturated fatty acids have double bonds which do not allow the carboxylic groups to stack over one another and hence remain as liquid at room temperature while the saturated forms of hydrocarbons do not contain double bonds which allow them to stack over each other thus forming solids at room temperature.

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
