Multiple Choice

Which statement about fatty acids is FALSE?

Fatty acids are composed of a hydrocarbon chain and a terminal carboxyl group.

Saturated fatty acids contain no double bonds between carbon atoms.

All fatty acids are essential and must be obtained from the diet.

Unsaturated fatty acids have at least one double bond in their hydrocarbon chain.

Verified step by step guidance

Step 1: Begin by understanding the structure of fatty acids. Fatty acids consist of a hydrocarbon chain (a chain of carbon and hydrogen atoms) and a terminal carboxyl group (-COOH). This is a fundamental characteristic of all fatty acids.

Step 2: Review the difference between saturated and unsaturated fatty acids. Saturated fatty acids have no double bonds between the carbon atoms in their hydrocarbon chain, while unsaturated fatty acids have at least one double bond in their hydrocarbon chain.

Step 3: Clarify the concept of essential fatty acids. Essential fatty acids are those that the body cannot synthesize and must be obtained from the diet, such as omega-3 and omega-6 fatty acids. However, not all fatty acids are essential; the body can synthesize many fatty acids on its own.

Step 4: Analyze the statements provided in the problem. The first three statements are true based on the biochemical properties of fatty acids. The false statement is 'All fatty acids are essential and must be obtained from the diet,' because not all fatty acids are essential.

Step 5: Conclude that the false statement is related to the essentiality of fatty acids, as only specific fatty acids are classified as essential, while others can be synthesized by the body.
