Afood label for one of your favorite snacks claims that the food contains only polyunsaturated fats. what can you infer from this claim? responses a. the fatty acids of the lipid molecules in the food contain more than one double bond. b. the fatty acids of the lipid molecules in the food contain the maximum possible number of hydrogen atoms. c. the bonds between the carbon atoms in the fatty acids in the food are all single bonds. d. each fatty acid in the food has only one carbon-carbon double bond.

A. The fatty acids of the lipid molecules in the food contain more than one double bond.

Explanation:

Polyunsaturated fats are a type of unsaturated fat characterized by the presence of two or more carbon double bonds (C = C) in its chain. Because they are unsaturated fats, they are usually found in liquid state at room temperature, but tend to be solid when cooled.

Polyunsaturated fats can have health benefits as they help reduce the levels of “bad cholesterol” (LDL) in the blood, and consequently lower the risk of cardiovascular disease. In addition, foods rich in polyunsaturated fats consumed in conjunction with foods containing vitamin E favor the removal of cholesterol from the blood by high density lipoproteins (HDL) and appear to reduce the risk of developing neuromotor diseases.

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
