(a) Interpretation: The hydrophobic and hydrophilic part of the 7, 10, 13, 16, 19-docosapentaenoic acid should be labeled. Concept Introduction: Fatty acids are long chain carboxylic acid , which may or may not have unsaturation in the molecule. They react with glycerol to form triglycerides. The reaction is known as esterification as a carboxylic acid group reacts with the alcoholic group to form an ester group. Unsaturated fatty acids can be defined as the long chain fatty acids which have a long hydrocarbon chain with −COOH group. In unsaturated fatty acids, the carbon chain must have at least one double bond.

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.
