Option C is the correct answer.
A fatty-acid molecule consists of a long chain of hydrocarbons with a carboxyl group at one end. It is a structural component of fats and oils. Saturated fatty acids have straight chains, while unsaturated fatty acids have bent chains due to the presence of double bonds.
A fatty-acid molecule consists of a long chain of hydrocarbons with a carboxyl group at one end. It is a structural component of fats and oils. The number of carbons in a fatty acid can range from 4 to 36, with common ones having 12-18 carbons. Saturated fatty acids have straight chains, while unsaturated fatty acids have bent chains due to the presence of double bonds. Examples of fatty acids include palmitic acid (
) and oleic acid (
).
