Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The type of lipid that contains at least one double bond is called?
A
saturated fat
B
unsaturated fat
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Unsaturated fatty acid carbon chains contain one or more double bonds with a terminal carboxylic group (–COOH), unlike saturated fatty acids, which contain no double bonds. These fatty acids are subdivided into two groups depending on the number of double bonds.

Detailed explanation-2: -An unsaturated fat is a fat or fatty acid in which there is at least one double bond within the fatty acid chain. A fatty acid chain is monounsaturated if it contains one double bond, and polyunsaturated if it contains more than one double bond.

Detailed explanation-3: -Unsaturated fats are usually liquid at room temperature. Vegetable oils, nuts and fish have mostly unsaturated fats. There are two types of unsaturated fats: monounsaturated and polyunsaturated.

Detailed explanation-4: -Unsaturated fatty acids have one or more double bonds. Each double bond may be in a cis or trans configuration.

Detailed explanation-5: -Oleic acid, shown above, has just one double bond, so it is called “mono-unsaturated”. Poly-unsaturated fats have multiple double bonds, are even more “bent”, and have even lower melting points. Saturated fats can impact your health.
