Verified step by step guidance1
Understand the structure of fatty acids: Fatty acids are long hydrocarbon chains with a carboxyl group (-COOH) at one end. They can be classified based on the presence and number of double bonds in their carbon chain.
Define saturated fatty acids: Saturated fatty acids have no double bonds in their carbon chain. All carbon atoms are fully saturated with hydrogen atoms.
Define monounsaturated fatty acids: Monounsaturated fatty acids contain exactly one double bond in their carbon chain, which introduces a kink in the structure.
Define polyunsaturated fatty acids: Polyunsaturated fatty acids have two or more double bonds in their carbon chain. These double bonds create multiple kinks, affecting the fatty acid's physical properties.
Compare the options: Based on the definitions, the type of fatty acid with two or more double bonds is a polyunsaturated fatty acid. Saturated fatty acids have no double bonds, monounsaturated fatty acids have one double bond, and trans fatty acids are unsaturated fatty acids with a specific configuration of double bonds.
