Question

what is meant by saturated and unsaturated fatty acids???

Answer 1

Saturated fats are solid at room temperature, while unsaturated fats are liquid at room temperature. This is because saturated and unsaturated fats differ in their chemical structures. Saturated fats have no double bond between molecules, which means there are no gaps and the fat is saturated with hydrogen molecules. On the other hand, unsaturated fats have double bonds, which break up the chain of hydrogen molecules and create gaps, allowing the fats to liquefy atroom temperature, according to registered dietitian Anne VanBeber, Ph.D, professor and chair of nutritional sciences at Texas Christian University.

Unsaturated fats are found in plant foods and fish -- monounsaturated and polyunsaturated fats are unsaturated fats. These good fats arefound in liquid vegetable oils, but not tropical oils, according to the American Heart Association. Stick with canola oil, olive oil, peanut oil and sunflower oil for cooking and food preparation to ensure you’re getting unsaturated fats. Oily fish – salmon, tuna, mackerel, herring and trout – contain a type ofunsaturated fat called omega-3 fatty acids, while most nuts and seeds contain a type of unsaturated fat called omega-6 fatty acids.
