Understanding Fatty Acid Structures

Steps:

• Identify the question focuses on properties or classification of two fatty acids.
• Recall fatty acids are carboxylic acids with long hydrocarbon chains, classified as saturated or unsaturated.
• Compare options based on chain length, saturation, or bonding.
• Select the option matching the correct description for two fatty acids.

Why B is correct:

• B accurately describes two fatty acids as having even-numbered carbon chains, per the biochemical definition of most natural fatty acids derived from glycerol.

Why the others are wrong:

• A incorrectly implies odd-numbered chains, which are rare in biology.
• C confuses fatty acids with lipids, not specifying two acids.
• D misstates saturation levels without evidence.
