For each food listed below, choose whether it has all single carbon-to-carbon bonds or at least one double carbon-to-carbon bond.

peanut butter
all single carbon-to-carbon bonds
at least one double carbon-to-carbon oil
all single carbon-to-carbon bonds
at least one double carbon-to-carbon cheese
all single carbon-to-carbon bonds
at least one double carbon-to-carbon

Peanut butter - At least one double carbon-to-carbon bond

The molecule that would represent roasted peanut used in peanut butter would be C57H104O6 which is triolein. It has three double carbon-carbon bond.

Sunflower oil  -At least one double carbon-to-carbon bond

The molecule that would represent sunflower oil would not only be one fatty acid but a combination of fatty acids wherein they all have double carbon-carbon bonds.

Cheddar cheese - At least one double carbon-to-carbon bond

Cheddar cheese is a mixture of different saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids. The unsaturated fatty acids would have at least one double bond in the carbon chain.
