Which of the following statements is true?
A)The omega end of a fatty acid molecule is the acid portion of the molecule.
B)Most fatty acids in food are water soluble.
C)A fatty acid is a polymer of glucose molecules.
D)A fatty acid has a chain of carbons bonded to each other and to hydrogen atoms.

Question

Quizplus · Accepted Answer

Fatty acids are composed of a long hydrocarbon chain (containing only carbon and hydrogen atoms) with a carboxyl group (-COOH) at one end, which is known as the alpha end. Therefore, the omega end of a fatty acid molecule is the end of the hydrocarbon chain opposite the carboxyl group (i.e., the methyl end). This is not the acid portion of the molecule, as the acid portion is the carboxyl group at the alpha end. Option A is incorrect. Option B is also incorrect because fatty acids are generally not water soluble, as they are hydrophobic (water-fearing) molecules. Option C is incorrect because fatty acids are not polymers of glucose molecules, but rather a type of lipid.
