Trans fats do not exist naturally, with a very few exceptions. Because the structure is uncrowded, they do not bend and so other newsround molecules and enzymes find it more newsround difficult to bind to them. The shape of the molecule is therefore vital to its function, much in the same way as the shape of a key is important for the operation of a lock. In fact, it is the very fact that they are straight that allows trans fats to solidify at room temperature. |

| These are unnatural compounds, science gifts which are known to be science gifts detrimental to health. In order to understand why, we need to consider some of the chemistry involved. (not too much, I promise). A natural, unsaturated fatty acid might look like the molecule below. It has several double-bonds between adjacent carbon atoms, which is what makes it "unsaturated". (saturated fats have no double bonds and all the "spaces" available are taken up by hydrogen atoms. (These diagrams are simplified for easier understanding) When this oil is hydrogenated, it is science gifts not possible to control where the hydrogen atoms are added to the structure. If both hydrogen atoms are added to the same side of the structure, it is called a "Cis" fat. |
