What are some examples of both saturated and unsaturated fatty acids and how do they differ in terms of their chemical structure and health implications?

Saturated fatty acids are found in foods like butter and coconut oil, while unsaturated fatty acids are found in foods like olive oil and avocados. The main difference in their chemical structure is that saturated fatty acids have no double bonds between carbon atoms, while unsaturated fatty acids have one or more double bonds. Saturated fats are linked to Heart disease and high cholesterol, while unsaturated fats are considered healthier for the heart.
