saturated refers to all single bonds in the hydrocarbon chain, meaning no kinks in the chain. The hydrocarbon has the most number of carbons it can have, as there are all single bonds. If the hydrocarbon has even one less carbon, there would be kink, and it would be unsaturated and liquid. Our body needs less carbon, so unsaturated fats are better. But having saturated fats means no liquid, rather solid, which means harder for the blood to get to the heart. So your risk would cardiovascular disease would increase
