How many double bonds does a saturated fat have?

saturated lipids and fatty acids have only single bonds, in order for it to be an unsaturated lipid or fatty acid, there must be at least one double bond present.

MY ANSWER:---

Dear sir,

I am a class 10 student and believe that your question only is not legitimate.How can a saturated compounds have a double bond.However,fats and oils have double bonds.(Unsaturated)

Here is a link I found on the net.It will help you understand better!!
