Fatty acids are carboxylic acids with a long, unbranched hydrocarbon chain
Fatty acids are carboxylic acids with a long, unbranched hydrocarbon chain. There are three main classes of fatty acids. Classify the fatty acids as saturated, monounsaturated, or polyunsaturated. Saturated Monounsaturated Polyunsaturated linoleic acid arachidonic acid oleic acid stearic acid palmitic acid
