Oil hydrogenation can produce a product, such as vegetable shortening or margarine, that is spreadable at room temperature because of an unusual bond that does not occur naturally. what is the name of this category of lipid?

I think the correct answer would be trans fat. These are lipids that are artificially made by adding hydrogen to vegetable oils resulting to a more solid oil. They are called partially hydrogenated oils. They can be found in pies, biscuits, margarine, cakes and doughnuts.
