|
They are more common in animals than in plants.
|
|
|
They have double bonds in their fatty acid chains.
|
|
|
They generally solidify at room temperature.
|
|
|
They contain more hydrogen than saturated fats having the same number of carbon atoms.
|
Detailed explanation-1: -Hence, the correct answer is ‘They have double bonds in the carbon chains of their fatty acids’
Detailed explanation-2: -Fats may be saturated (having single bonds) or unsaturated (having double bonds). Unsaturated fats may be cis (hydrogens in same plane) or trans (hydrogens in two different planes). Olive oil, a monounsaturated fat, has a single double bond whereas canola oil, a polyunsaturated fat, has more than one double bond.
Detailed explanation-3: -The answer to the question is b. Unsaturated fatty acids always contain at least one double bond between carbon atoms.
Detailed explanation-4: -Answer and Explanation: The source for the unsaturated fats is plants rather than animals. Therefore, this statement is false. The double bonds are present in the carbon chains of the unsaturated fats.
