Many people believe that saturated fats are saturated because they contain extra goo, glob, oil, fat, or a combination. In reality a saturated compound contains all of the hydrogen it can. Unsaturated fats can be converted to saturated fats by reacting them with hydrogen gas under the right conditions using the correct catalyst. Saturated fats have a higher melting point than unsaturated fats so are harder for your body to deal with.
