What are the two types of fats you can find on a food label how do they get their names

The four types have different chemical structures and physical properties. The bad fats, saturated and trans fats, tend to be more solid at room temperature (like a stick of butter), while monounsaturated and polyunsaturated fats tend to be more liquid (like liquid vegetable oil)

Ithink that its like 15 mph.
