Verified step by step guidance

Understand the structure of fatty acids: Fatty acids are long hydrocarbon chains with a carboxylic acid group (-COOH) at one end. They can be classified based on the presence and number of double bonds in their hydrocarbon chain.

Learn the definition of saturated fatty acids: Saturated fatty acids have no double bonds in their hydrocarbon chain, meaning all carbon atoms are fully saturated with hydrogen atoms.

Learn the definition of monounsaturated fatty acids: Monounsaturated fatty acids contain exactly one double bond in their hydrocarbon chain. This double bond introduces a kink in the structure, affecting its physical properties.

Learn the definition of polyunsaturated fatty acids: Polyunsaturated fatty acids contain two or more double bonds in their hydrocarbon chain, making them more unsaturated than monounsaturated fatty acids.

Understand the term 'trans fatty acid': Trans fatty acids are unsaturated fatty acids where the hydrogen atoms around the double bond are on opposite sides (trans configuration). This is different from the cis configuration, which is more common in natural fatty acids. A trans fatty acid can be monounsaturated or polyunsaturated, but the term 'trans' refers to the configuration of the double bond rather than the number of double bonds.
