I could be wrong but a vitamin is not a lipid. A lipid is a fat. Vitamin A could be a fat soluble vitamin, but I am not sure if it is. According to my Chem book, Vitamin A is a fat-soluble vitamin and is classified as a lipid. The lab book says to puncture a vitamin A capsule or use cod liver oil, so my guess is it is a triacylglycerol, i.e. an oil.
