Oleic acid is the most common naturally occurring monounsaturated fatty acid, found abundantly in olive oil. The fundamental structural formula for a monounsaturated fatty acid defines its chemical properties and biological function, distinguishing it from saturated and polyunsaturated fats.

Approximately 95% of naturally occurring unsaturated fatty acids feature one or more C=C double bonds, a defining characteristic of their chemical class. This is the fundamental chemical trait that answers the question: does unsaturated have double bonds? The presence of these bonds dictates their molecular shape and physical properties, which in turn influences everything from their physical state to their biological function.

The physical difference between a solid fat and a liquid oil at room temperature is determined by its underlying fatty acid composition. The intricate chemical structure of these molecules, including their chain length and saturation, is what factors determine the properties of fatty acids, influencing everything from their melting point to their biological function.

Though fatty acids are crucial components of lipids, providing a dense source of energy, they do not differ significantly in their average caloric content per gram, which is approximately 9 calories. The variations among them lie in other fundamental structural and chemical properties that dictate their physical and metabolic characteristics.

Over 50% of animal cell membrane mass is composed of lipids featuring fatty acid tails, and the critical difference between saturated and unsaturated fats is rooted in their atomic structure. The singular chemical feature that makes a fatty acid tail unsaturated is the presence of one or more double bonds between its carbon atoms.
