Verified step by step guidance

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 between carbon atoms.

Review the types of fatty acids: Saturated fatty acids have no double bonds and are fully 'saturated' with hydrogen atoms. Monounsaturated fatty acids have one double bond, meaning they are missing two hydrogen atoms. Polyunsaturated fatty acids have two or more double bonds. Trans fatty acids are unsaturated fatty acids with a specific configuration of the double bond.

Focus on the key characteristic in the question: The fatty acid described is missing two hydrogen atoms and contains one double bond. This matches the definition of a monounsaturated fatty acid.

Compare the options provided: Saturated fatty acids do not have double bonds, polyunsaturated fatty acids have multiple double bonds, and trans fatty acids are a specific type of unsaturated fatty acid. The correct answer is monounsaturated fatty acid.

Conclude that the fatty acid described in the question is a monounsaturated fatty acid based on its structural characteristics (one double bond and missing two hydrogen atoms).
